When your ball sweat has that stinky tinge of vinegar and asshole. Sometimes it seems to be accompanied by a faint scent of bleach. It can also smell like leftover pussy from the night before. Either way, your balls, or the satchel that contains your balls, smell like hell
I cant stand that bitch, so the next time I get her to blow me, im gonna make sure I got some nice ROT SATCHEL ready for her
