n. A driver who accelerates when you signal to change into their lane,
even though they have a lot of space to let you in. Very common in
Los Angeles driving. Seeing your turn signal, they instinctually step on the
gas, and get right up your a**, like a suppository.
I
almost had a bad accident because I
changed lanes and that signal suppository nearly rammed into me!
It's so
hard to change lanes because of these signal suppositories!
