deep friends 

Friends who go DEEP, in more ways that one ;) Bestie with benefits, but to everyone else's knowledge we're "only friends"

"Yea, Me and ______ are deep friends "

Spectator #1 "So they are just "friends", huh?"
Spectator #2 "My thoughts exactly, they totally go DEEP"
Spectator #1 "Mhhmm, best friends. DEEP FRIENDS I would say!"

When a person accepts a shit into his or her mouth from another, usually a close friend.

Those two guys were really close, did you know they gave each other deep friend mars bars for christmas?
