A secret phrase between two men at a social gathering or sporting event where they can alert the other that a chick with nice breasts is in the vicinity without alerting those around them. The term is simply boob minus an o. Boob-o=bob.
1st Dude: "Hey look there's Bob!" (Points at breast)
2nd Dude: "I am so glad he could make it. I was worried he wouldn't."
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
