Someone whose tongue is sticking out on their picture or icon on your phone. Every time they message you, it looks like they are licking your screen. Not to be confused with the below average and desperatewindow licker. A screen licker is a whole 'nuther level of licking!
When he messaged me, it looked like he was licking my screen.... he is such a screenlicker ;)
A guy or girl who participates in a particular scene/fashion cult/band worship in order to have sexual intercourse with the other members of that scene or social group.
