look up any word, like half chub:
Noun. Bestest Buddy
See Miss Megan? She's my BeBu. We have been friends for years.

Short term for "Best Bud" or "Best Friend"; using the first two letters of each word. Great for describing a get together or a special event with best friends.
Are you busy Saturday, because I wanted to have a bebu beer and stripper night.
