Anyone ever say, "go suck a roach?"
My siblings and I use to. Because I thought it literally meant a nasty insect, makes it gross, huh?
Just recently, I learned what a "roach" was (in terms of smoking weed)... I don't think my parents knew what it means, either... or, was I correct when I thought it referred to the creepy, crawling things that can make a jittery soul jump up on a chair? You know, those huge tree roaches that fly.

"Roach" was what you said when you let gas, and "pokes" was what the others, who got to enjoy the effects of the explosion between your legs, said right before they knocked a knot in your upper arm, big enough to stop blood from getting to your hand.

How about 'slug bug,' another term shouted out right before slugging or getting slugged, when a Volkswagon Beetle was in sight.
