What is Not Gay?
Adding (Not Gay) to something, regardless of its content, makes it completely heterosexual.
Guy 1: "My penis is very small and smells of prawns, my friend who I experiment with (NOT GAY) says it makes him feel sick to suck it, but his penis is nice, I like to suck that. I know I can't make my penis bigger, but I want it to stop smelling of prawns, I shower every other day and spend 5minutes with a sponge doing vigorous rubbing untill my end is sore, but no it still smells. help?"
Guy 2: "There goes a man who is completely heterosexual."
