An absolutely huge ball sack, round and plump to the point of nearly exploding, similar to a bloated stomach. Often veiny and riddled with shallow wrinkle lines, in extreme cases it resembles a beach ball from the 1960's, overly inflated to the point of bursting. Usually smells like a cross between undercooked pork and horse hoof.
He mistakenly put his bloatus in my face, thinking I'd be able to get that huge stinking sack of potatoes in my mouth.
