A little round ball of shit (and/or bumwad) stuck in the hair of the crack of your ass and WILLNOT come out.
I gotta trim the hair in my ass crack 'cuz I keep gettin willnots. I really had to reef on 'em last time I wiped my butt, they were so tangled up.

An amount of feces that remains on your ass hair that will not come off around your anus that have dried that you could not wipe off properly and it hurst to pull them off.
Damn! Those freaking burrito's gave me some damn willnots! I wiped but I can't walk without the friction pulling on my ass hairs!
