A brosome is a sexual encounter including three or more bros. But since this act would make all involved no longer bros, the word is considered void in conversation as soon as it is used in this context.
Man, I totally had a brosome with Dylan, Christian, and Magoostus last night!

Brosome combines the words "bro's" and "awesome" together. Two induvidually very strong words that really belong together, making one hell of a word!

Brosome is a word to describe awesome stuff you do with your bro's.

- A good night out with your bro's may be referred to as brosome! (cause it has the two elements "awesome" and "bro's")
- Going to the movies with your girlfriend may NOT be referred to as brosme. (cause its lacking the bro-element, well its actually lacking awesome too)
That trip to Amsterdam was brosome!

The game tomorrow will be: BRO- wait for it.. SOME! BROSOME!
