Jfkd

Acronym.

J: just
f: fucking
k: kayla
d: don't

Used in a sentence: Kayla I'm so done with your attitude JFKD!

when you say it you add a pause after the just, so it kind of sounds like

Just, .........Fucking Kayla, don't .

It's almost like Kayla has so much sass you just don't know what to do .
