A derivation of greasy characterized by a disgustingly overwhelming amount of moxie towards even the most ordinary facets of life. Usually with an affinity for unorthodox hobbies including, but not limited to sword collecting, ant farm building, magic card trading, and beanie baby making. Hard to describe, yet easy to recognize, the gretchum kid will be the one who everyone wonders how he's still in public school. "What is that kid's deal?" or "What the hell is he doing?" are common question when eyeing a gretchum kid.
"Someone go tell that gretchum kid to stop eating the all the cheetos. He reeks like a past date jar of velvetta cheese thats been in a kiln filled with dead animal carcacuses for around 3 days."
