When you pull a guy's unwashed cock out and it smells like a jar of expired warm mayonnaise.
Slut: I tried sucking this guy's cock last night, but it smelled like warm mayonnaise and I blew chunks all over his dick, he grabbed my face and skull fucked me anyway.

Get the Warm Mayonnaise mug.
When a vagina is so loose you can't feel anything just warm moistness. Like you had a taken the cover off a jar of mayonnaise and stuck your penis inside.
Rick: Hey you hit that chick last night?

Mike: Yea....

Rick: How was it? I bet she was tight.

Mike: Man that chick was a warm jar of mayonnaise.
