Bellybutton Trampoline 

When a chubby person wears a shirt that is too tight for them, and the material stretches tightly over the large recess in their stomach which leads to their bellybutton. The tightly pulled material yields a 'trampoline' effect over that area.

That fat chick has some serious bellybutton trampoline going on with that shirt.
