Hooking up with someone whom you know -for whateverreason- is someone you really should NOT be hooking up with.
It's 8AM Sunday morning, you're doing the walk of shame in last night's clothes... or what's left of them.
There's only one thought going through your head as you try to remember where your car is:
Dammit! I Make Bad Life Choices.
"Bad Life Choices" are usually sex-life related and tend to fall under having 'sexual relations' with 1 or more of the following; your boss, a co-worker, a cousin, a friend's lover, your mom's boyfriend, your ex's sister, a known player, total stranger or a random groupie and/or friday night ho, etc. etc. etc.
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?"
