This word is derived from a song by group x. In context, the word was used in a mocking tone by Hashmir who was reprimanding a kid, this Bobby McPrescott (actually Blade from the band), who was complaining about physical ailments because (as Hashmir deduced) he failed to eat enough cheese to be healthy.
Bobby: All the kids at Eddie's are sayin' my bones are astrew, and that my arm... my arm looks like a garbage truck.
Hashmir: Oh, oh its right Bobby McPrescott. You know you're not eating a lot of cheese thats why. You're supposed to eat something like 14 hundred gallons per day or something.
