When a woman has a yeast infection and masturbates leaving a thin crust of cum to be eaten.
No thanks I'm not hungry, I had a crusty tuna earlier.

Get the crusty tuna mug.
That chick has CRUSTY TUNA between her legs. ;
Her vagina doesn't STINK like (CRUSTY TUNA ) IT STUNK like CRUSTY TUNA

Someone toss her some douche , she smelled like CRUSTY TUNA
If she smells like CRUSTY TUNA don't touch it she needs a pap smear!!!
