You must win 5 consecutive ranked Tug of War matches on Xbox Live. Whether or not you achieve it will mostly be down to the luck of the draw. Just hope and pray that you get matched with 5 people who aren't as good as you are.

TIP: Don't try to act "l33t" and play above your skill level. Select a difficulty that you are comfortable with. For example, I can play expert guitar, but it doesn't mean I'm any good at it, whereas I can full combo 99% of the songs on hard. So, I choose hard.

An easy way to boost this achievement is for you & a friend to play on Easy Bass or Guitar. Since no one plays RB1 that much anymore, it really isn't too hard to find your friend...even in a ranked match. My friend & I have boosted this on Easy Bass and Medium Guitar without any problems.
