@zenitix: I can hear him saying "mom's forgetting".

Besides, how does spaghetti even fit into the song anyway? The way it would be placed doesn't even make any sense, "my mom made spaghetti, and now here's a legitimate message."

@Chameloshi: It does make sense for it to be spaghetti, because he's saying he puked on himself, "There's vomit on his sweater already, mom's spaghetti", I think the line is to convey a scared nerdy kid.
