Greg is fat ass bitch who needs to go outside. loud enough to be obnoxious, and super short. Not a ladies man whatsoever but oh well, he has a solid 2 friends. his mum, and his dad.
A "Greg Grunzel" is someone who represents the highest and most purest form of complete trash. This person provides zero value to anyone and has no real purpose in life. Most likely born in a dumpster in Erie, Pennsylvania.
