How to unlock the ROBBED ZOMBIE achievement in Left 4 Dead 2 - Definitive Guide
This is done on the "Dead Center" campaign: Chapter 2
The easiest place to collect these is when you have to get the Cola for the GunShop owner. Instead of giving him the Cola, sit outside the store and just wait for the CEDA agents (they wear blue or yellow HAZMAT suits) to come along with the packs and packs of zombies that will pour out. You should get a CEDA agent every other crew of undead that come out looking for you; if you're lucky you will get one from every horde that comes out.
You should have the achievement in about 15-20minutes of opening the door, if not wait a little longer and it will be yours.
NOTE:This is best done on easy, no need trying to be a hero. Also if you don't see many vials don't worry, the game director is all random. It might bring 10 vials in a row or it might not bring any.

This is the perfect area for this. Took me about twenty minutes for it. Got a drop around every five or six CEDA agents!

I got it just playing the dead center campaign multiple times, but this sounds like a good place for it, positive vote.

This achievement must be done in the Dead Center campaign. Occasionally you will come across CEDA agents (men in big green / yellow suits). After you kill them, sometimes they will drop a vile of Boomer vomit. Do this 10 times and the achievement is yours.
Note: You do not have to be the one to kill the CEDA agents. If a teammate kills them, picking up the vile still counts.

Is there a special way you have to kill them because every time I kill one nothing falls out

It's a hit or miss. Sometimes they drop it, sometimes they don't. If they have it, you'll see it on their belt while they're walking around. Same with the nightsticks on the SWAT infected.

I actually just found a way to idle this on accident. Not that it's really needed. I was doing as solutions stated above, Dead Center - Chapter 2 (Streets). Play up to when you have to retrieve the cola, open the store door, but don't go in, just stand outside and kill the waves of zombies, group with your AI, and they will protect you. I was playing Campaign, instead of Singleplayer, so when I paused to go do something else, I was expecting to come back dead, but my health was still in green, and saw like 5 Boomer Bile containers lying around on the ground, I went around and picked one up, threw it, and picked up the next, etc. I went to check my achievement progress and I had went from 0/10 to 5/10 during the 10 min. period I was gone. Then I healed myself, and idled the rest.

Always nice to be able to idle with silly collective achievements like this. Thanks for the tip!

CEDA agents are the zombies wearing full body suits. If one drops boomer bile when it dies, pick it up. CEDA zombies only appear in the first 2 chapters of Dead Center, so keep replaying them until you get 10 boomer bile drops.
Replay the beggining of the Dead Center campaign making sure to kill and search the zombies in the hazmat suits. Go through every room in the fire area to look for these guys. Not everyone of them has a boom vial on them. Once you go outside, it is best to restart the campaign since there are less and less of them throughout the campaign. Send me a friend request over live if you need help.
If you've got the Sacrifice and 5-10 minutes you can get this easy. Load up the first chapter of The Sacrifice campaign and progress right until you reach the area where you need to release the tank from the train car. Along the way if you happen to find a bile jar, keep it. There should be a bunch of CEDA zombies in the area already, all you need to start is one jar of bile. Toss said bile jar on the grassy area right below the ledge where the train car is and a mini horde will climb over the train car, 40-60% of which are CEDA zombies. There should be at least one bile jar per horde, I've seen up to four in one horde. Repeat the process of throwing bile, killing horde, and picking up bile and you should have the achievement in no time. Should you run out of bile, you can try to summon a few more zombies using pipe bombs or just reload the map. Difficulty shouldn't matter, though I did this on normal.
As said before the area to do this is definitely on chapter 2 (streets) on the dead center campaign. What you may not have known however is that the collecting is cumulative. For example i only collected two vials when going for this achievement which means i must have had 8 previously collected. Hope this helps.
Always look for the Hazmat Infected while running through Dead Center. As soon as you see them check around their bodies once you kill them to find Boomer bile. They don't always have these canisters so this may take several attempts to do.
Once you find the bile pick it up and either user it, or you can hold onto it and wait until you find another Infected with more bile. You can then use the bile you have and pick up the freshly dropped bile.
Repeat this 10 times for the achievement to unlock.

In the "Extinct Center" campaign, you will come across infected people in bio-suits on your way. Some of them you will notice a vomit bomb on their belt after killing
such an infected person needs to pick up this bomb. Pick up a vomit bomb from ten infected people and you will receive the achievement.

To get achievements faster, there is one way that I used. In the first chapter, when the guard asks you to go to the store for a cola, and when you open the store, the siren will start screeching and the infected will run towards you in WAVES. (Measured by waves)!!! I did this, took the bottles, threw them at the guard's door (without giving them back yet), went downstairs and began to sit and wait. There will be endlessly infected people, in waves, and among them there will be zombies in suits. Kill and loot.
