fuck the mashed potatoes 

Slang for the act of ruining a meal for the other diners. Generally used in the context of a dinner party at a private residence, but can also apply to a meal enjoyed in a restaurant.
A more general definition applies when someone manages to spoil an event for the group by doing something very inappropriate.

Every time my girl and I double-date with James and Amy, We end up leaving early because James always manages to fuck the mashed potatoes by drinking too much and starting a screaming match with Amy about who spends to much money.
