When you act like a little crybaby that only wants to do things how he or she wants. And if you help that person one time you will get stalked. Also a LipLip show depressive behaviour around 2 O'Clock.
Sarah: "Just ignore that person he/she is acting like a LipLip"
Megan: " Oh No!! It's almost 2 O'Clock LipLip Time"
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?"
