flex stop

When you cross your legs and flex your butt muscles together to hold a dump in because your anal sphincter isn't strong enough.

Dude I had a close call this morning. I broke into a shuffle on the way to the bathroom and had to pause half way to do a flex stop.

flexabetes

The disease of having so many gains, that you just can't stop flexing

I was in the store... When my flexabetes kicked in and I started flexing on a 3 year old.
