When there are a bunch of topless women in a hot tub.
After returning from the bar, there was always some boob soup at the beach house.

Get the Boob Soup mug.
When a well endowed women with saggy, structure-less boobs wears a low cut shirt, causing them to appear not as individual boobs but instead as if her bra is a bowl filled with liquid boobs.
Sarah needs to realize she can't pull off those low cut shirts anymore, after nursing three kids she's just showing off her boob soup.

Get the Boob soup mug.
Boobs that are so big you could use them as a tray to hold food.
'Crap! Don't make me laugh. My tray'll slip off my boobs! Oh no, I spilt some soup'
*LICKS*
