Being at a certain point of desperation where you'll reach over to another
table and help yourself to the unfinished drink of someone who's
left the lounge. Common practice of stressed-out folks about to head into a sales call, going through divorce, or just want to put the "seed" in "seedy", and need that
extra drink. Usually practiced after one has had a couple of drinks (to, ya know, establish that you "belong" in the establishment), and desperately reaches for some abandoned beverage in a
knee-jerk, fuck-all gesture.
