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."
