Cold nut

A "cold nut" is used to describe a sexual interaction with a female that bore no romantic feelings.

i.e. hooking up with a random and not calling her back. You have no intention of starting a relationship but you still
wanted to smash, so you give her a "cold nut"... a nut that lacked the warmth of love.

This would apply to hooking up with an ex that you no longer have feelings for.

It can also be the first major sign of a relationship in decline.

Example: "Man I wasn't into her but she was thirsting hard so I just gave her a cold nut."
