(n): A liquor parlor shot made out of 1/2 vodka, 1/2 RumChata, served in a salted rim shot glass. The etymology of the shot came from a conversation amongst friends when in the hypothetical accident in which one man sticks his dick through a gloryhole and instead of receiving a mouth on the other end, the said penis is actually head-butted by another receiving penis. After a few moments of the two penises rubbing against each other, one (or both) of the man's penis(es) achieve premature ejaculation or pre-cum.
The actual liquor shot combination with the salted rim actually achieves the accumulated taste of a white chocolate pretzel.
Logan (coming back from the men's bathroom): Hey, did you see that hole in the wall in the bathroom? It looks like a gloryhole.
Nick: Yeah, I saw that. Hey, imagine there's two guys each on the opposite sides of that wall and at the same time they stick their dicks through the hole, touching at the same time.
Logan: That's disgusting!
Nick: Even worse, as they accidentally touch dicks, they get a pre-cum.
Logan (gagging to hold back his mouth-puke): We should create a shot of that. Hey, Barry (the bartender). Can we get a 1/2 shot of vodka and a 1/2 shot of RumChata with a salted rim?
Barry (pouring the shots): What do you call these shots?
