The process where a male puls his testicle and dangles it just over the top of his trousers so it looks like a brain. then the mail raves around the room. also brains can be used to describe a testicle.
Wow me nd the lads were having a Brain Dance round the room last nyt!

I was walking round last nyt with my brains out.
