Pimp spit stories
Stories that are over the top, possibly uncomfortable and embarrassing. It's based on the Friends episode, where Paul Rudd (Mike) takes Phoebe to meet his parents and she tells a story about how she has Hepatitis because a pimp spit in her mouth.
I was on a date and this guy was telling ridiculous stories about fighting, like being outnumbered 6 to 1 and using a baseball bat in fights, and I was just like, could we have less pimp spit stories please.
