knife soup 

A kitchen sink of soapy water with sharp knives hiding in its depths.

Darling, can you wash the dishes? No problem love.

Arghhh I've cut myself. You didn't tell me it was knife soup!!!

Soup Knife 

Used to describe a person who is socially awkward and serves no real purpose in a group of friends.

Originated when a group of friends were spooning on a trampoline and there was one friend who was not in the spooning line. This friend was called the soup knife for he was not a spoon.

On Malka's Trampoline:

All: This is a great spooning session.
Jalen: Roy, Why aren't you in this line?
Roy: No, I'd uhh rather kick it and do uhh nothing.
Lauren: (Obnoxious Laugh) You're such a soup knife Roy!
