Thunderpants may be a bit difficult in my household, where I am known for the loud, smelly, gaseous poo particles that regularly and rapidly exit between my gluteous maximus.

I wear Target brand black undies. Grundies. Normal undies.

I'd rather not have floss running up my backside. Floss is for between teeth (and not from hair either). One of my girlfriends swears by g-strings for playing basketball. Me? I'd sure be running, but for the bathroom to pull them out... mind you I'd have a moose hoof rather than a camel toe, as I'm a much larger woman...
