An ambiguous term referencing not a lesbian, but a nubile movietheatre employee, who at the urgence of a veteran coworker, licks a plant to confirm its authenticity.
Basically a person who licks pants, but also has come to be used as following:
A person who is determined to squeeze everything they can out of a situation.
Used in the commercial "Pop Tarts - Pantlicker (2002)".
A man is in his office eating a Pop Tart Pastry Swirl and the filling spills on his pants and he takes them off. But then the cleaning lady walks in and sees him trying to lick the fruit off of his pants and she gives him that dirty look and says, "Pant licker!"
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
