URINALYSIS: \YOU rinn al is is\ noun: Careful inspection of a surprisingly open seat on a crowded subway for bodily fluids or spillage.
USAGE: Against all logic, there was an open seat on the uptown 6 during rush hour, but upon closer inspection, someone had clearly marked their territory.
This is one of my favorite WoW’s yet but you didn’t use it in the sentence.
There has to be another word for when you have performed your urinalysis, it comes back negative, but when you sit down you know damn well there is something wrong with that seat everyone knew but you.
