To give someone a "gretz-ing" is to let someone know they are retarded/ or have done something that makes them look retarded. Based on a early 80's public service commercial featuring Wayne Greztsky and a mantally handicapped teenager.
Scratch the side of your head really fast like you have fleas and exclaim to the nearest stupid person "Gretz!"

The act of immediately criticizing someone's work regardless of quality or craftsmanship.
I baked a casserole the other night but my wife was gretzing the fuck out of it.
