Break the word down.
Bum - Ass
Skeet - Sperm
That does NOT mean close friend!
So basically, calling a friend a "bumskeet", you're calling them ass sperm.
Stay away from the internet.
There are no examples, nobody use this word. It's really, really fucking dumb. Bum skeet, nobody can use.
1. (N) A really close friend.
2. (V) To hang out and have a crazy awesome time.
1. " Name Name & Name, BUM SKEETS FO' LIFEE! "
2. No one can bum skeet like we can!
