A frozen dinner that, when nuked, smells like ass.
"Dude, what's he cooking for lunch, an asserole??"

"Yeah, I don't know how he eats that crap!"

A big crap or load of diarrhea. Mainly occurs soon after eating a big meal and may contain strange combinations of identifiable chunks of food as is with a casserole. Props to Lumpy.
Man, after eating that #1 from Burrito King, I gotta go make an asserole.
