dack elastic - The stretchy part of your pants that saves you from embarras

The stretchy part of your pants that saves you from embarrassment when you sit down in public.

I sat down in a restaurant and my dack elastic saved me from a pants disaster.

My dack elastic is the reason I don’t have to explain why my pants are falling down in front of my boss.

I wore my pants for three days straight and my dack elastic is now a legend.
