dack elastic - The stretchy part of your pants that gives you hope when you

The stretchy part of your pants that gives you hope when you’re eating a burger and your pants are about to burst.

I ate three burgers and my dack elastic is about to scream and quit.

My dack elastic is the only thing holding my pants together after that third slice of pizza.

I told my dack elastic it was the best part of my pants. It just stretched and said nothing.
