committed snack

A person with whom you are in a committed relationship, yet you are not an official couple (boyfriend/girlfriend).
This may include sexual relations or not.

In other words, you are both attracted to each other and like spending a lot of time together.

This term is inspired by TikTok content creator Gabrielle Chase.

Person: "I see that you have been hanging out with that guy a lot. Are you dating now?"

Me: "No, but he is my committed snack."
