Having a mexican best friend, being a mexican yourself.
Derived from the word Beaner.
You use this word when you want your friend to do something they don't want to do.
Friend 1: Wanna go to the store with me real quick?
Friend 2: Nah I'm gonna stay, go alone.
Friend 1: Dude. Bean Buddies, come on! Bean Buddies dude!
Friend 2: *after thinking a bit* Ok! lets go.
