"slutty buddy" 

Friend with benefits. A woman who appears to be conservative but secretly is someone's lover, i.e. slutty buddy, or friend with benefits, secretly has a secret lover and has sex often, outside of any more meaningful relationship.

She seems uninterested in guys but I bet she is someone's "slutty buddy".

slutty buddy 

A friend with benefits. A girl who seems conservative but secretly has sex with one guy and acts really slutty about it.

She doesn't seem tempted even when she's drunk but I bet she's someone's slutty buddy. She can't be that composed if she hasn't gotten any in 5 months like she says!

Smutty Buddy 

A smutty buddy is a friend that you treat like shit but still get along with really well.

Rob: Driving Golf Cart, notices Beebo hanging of the side laughing and having a good time, and snatches the wheel to the left flinging Beebo through the air just to smash into the pavement...Rob laughs uncontrollably. When he realizes his friend is laughing too he proclaims "ahhh That's my little smutty buddy. "
