When you look at someone and you think wow that guy's dirty.
This could be attributed to outer appearance or actions such as having a dirty mustache, driving an
IROC or wearing an acid washed
jean jacket.
Also can be used when referring to a meal, such as a KFC double down, or a super big mac followed by a 20 piece
chicken mcnugget.
Look at that gressy son'a'bitch over there...
Soo greesy!
That
meal was greesy!
