Two men become non biological brothers when one or the other has sex with either thier wife or girlfriend at one point in time. One can also become a snowman brother if the two men enjoy any erotic part of a woman.
Daniel- Hey man, did you have sex with my girlfriend?
Xavier- It was a long time ago and I hope your cool with it.
Daniel- Dude, its all good. We are Snowman Brothers now!
