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!"
Utility beer is the beer you keep around for the day-to-day moments when beer is a necessity to assist in pedestrian activities (golf, plumbing, yardwork, babysitting, staff meetings, Zoom calls). For the beer snob it is the beer you save for neighbors when they drop in at 3 p.m. on a Tuesday. It is differentiated from the actual high-end beer you save for special events, holidays, and special tastings.
Person 1: Dave, did you bring along those hazy craft IPA's so we could drink while cleaning Lyle's pool?
Person 2: Nope. I just have a bunch of utility beer that Steve dumped on me. Good enough for this. It is only 10:30 a.m.
