The name for when a person laughs so hard that they suck in so much air, they are a balloon. And they can explode from being so stupid.
ALTERNATIVE: A man sucker, if you know what i mean.
The kind that gets picked up on the classiest of streets. But stupid for being there because he cant afford the right clothes to look nice, so no one picks him up, which makes him stupid like a balloon and he explodes from stupidity.
