when you use your penis like a knife and scoop some butter with it then smear it on someone's anus and then have anal sex with that person useing the butter as a lube.
Doug went out with Smeegal last evening and he said that he was butter in the buns before they went out for dinner and a romantic movie.

Rolling back to the 1970's joy of sex book,a buttered bun is the highest bond between two male friends. To have sex with a woman, cum inside her, and have the other male have sex with her right after him and let his cum get all over his penis.
