stunt undies

Underwear a girl will leave behind for the guy she just slept with, to think that he scored with a really fat chick or with a really skinny chick.

Heath thought he slept with a girl who was a size 6 but come to find out she was a size 4 according to her stunt undies.

Undying Fidelity

"Undying Fidelity" was one of the last words/phrases told by Loki to his brother Thor in the Avengers: Infinity War movie in May 2018.

It was also used by Loki's fans and Tom Hiddleston stans to create a movement in Twitter to show the Russo Brothers their love for the said character.

I will forever cherish your undying fidelity for that man.

The hashtag, #UndyingFidelity, was used by some Twitter users to show their love for their favorite character.
