Tuna stink valley
A pussy that stinks like tuna and has not been waxed/shaved for some time
Bleedry's pussy is the ultimate tuna stink valley
Stink valley
The valley between the butt cheeks that leads to the source of the stink hole that often becomes sweaty and stinky. Ie.. the butt crack
On a hot day I find I get a very sweaty stink valley.
