"Don't drink the Kool-Aid"
by Nugget April 26, 2005
Comes from a religious mass suicide from poisoned kool-aid. When people are going to a meeting of a controversial group, they are sometimes warned not to drink the kool-aid
Oh, you're becoming a scientologist? That's ok, just don't drink the kool-aid.
