Someone who commits acts of grime, not terrifyingly grimy, but quasi-grimy...such as stealing a drink that is left unattended at a
bar. Or eating a roomates last slice of pizza they were saving for after thier part time shift at Barnes and Noble.
It is dervied from Grimaldo Used Auto Sales on
Chicago'
s illustrious Archer Avenue.
Grimaldo himself is not a known grime, however he is the root behind the word. WHo would want to purchase a used car from someone named "Grime-
aldo"
Jay just chugged that douche bag's
beer he left unattended at the
bar, what a grimealdo!
We walked in on west jerking off to some girl's myspace page, he is a
straight grimealdo.
