Make Way

There is a weapon that shoots green blobs and when you drive over them, they will stick to your car slowing its movement, unless you shake them off by toggling the thumbstick back and forth. To get this achievement, simply drive over 3 or more blobs in quick succession before shaking them off. They can either be blobs from an opponent or your own. An easy way to do this is if you get the blob gun, just quickly fire them all in a line then drive over your own blobs.
