look up any word, like smh:
 
1.
the act of becoming brothers with a good friend after each friend having seen the others balls whether the friends like it or not; they do not have to see each others' testicles at the same time.
Dude, I walked in on Homer taking a piss yesterday and caught a glimpse of his balls; God i hope he never sees mine because I don't want us to become balls bros.
