The situation when one is
engaged in a threesome and two of the participants become extremely into each other, neglecting the sexual needs of the third person and
eventually ignoring them almost entirely. Derives from the scenario in which one is enjoying a fast food meal and
immediately devours the burger, only to neglect the side of fries until later, leaving them cold, jealous, and a little salty.
"So you hooked up with Dillon and Spencer the same night?"
"Yeah, but I was
definitely the cold fries, they were way too into each other."
"Bro, you made it with
Katie and Sam at the same time?!
Legendary!"
"It was cool and all, but I think Katie was feeling like the cold fries, kind of killed the vibe."
