bust a gut

To laugh so hard your stomach hurts.

George Carlin was so funny last night I nearly bust a gut.

bust a gut

Eating a very large meal; eating so much that ones stomach is so full that one feels that it might actually break open. Often times this feeling results in one falling asleep while watching t.v.

I ate so much I thought I might bust a gut.

Let's go to that new Mexican place and bust a gut!
