1.
A person who sits next to you in a public bathroom stall to take a shit, when there are options to sit one stall away. So if there are three stalls and you are sitting in stall 1 ...the grinch would sit in stall 2, EVEN if stall 3 is open and clean.
Dude I was in the work bathroom taking a dump and David came in and totally grinched me.
