Essentially,
masturbation fodder you're never
going to bed.
Derived from the supposed similarity in appearance between semen or female sexual fluid and
vanilla yogurt.
"I merely insulted your yogurt cup! I don't find
Jessica Simpson attractive,
that's all!"
"My boyfriend is your yogurt cup?! He's mine!"
"Scat? Wow, you have the sickest taste in yogurt cups."
