A nicer term for a butt-buddy.

Beau is awesome. Beau is amazing. They are the type of person to light up your day when it is dark, and to be there for you when you need it most. They are definitely the type of person you want to be around. She is cute, funny, and overall an amazing person. They don't know how cool they are, but everyone else does. People smile just thinking about her and if you know a Beau, be sure to keep them in your life.
Beau is so cool!

Person 1: Dang he’s a ladies kinda guy, that Beau!

Person 2: I know right!
