Short for, "Just kidding, all the way". It is used by many of the same people who say things like, "See you later, alligator" and "Bye-bye butterfly". It is presumed that the kind of people who say these things suffered some sort of serious rhyme shortage as children.
"Hey, did you hear? Jerry just got hit by a car!"

"Haha, you fell for it! JK all the way!"
"Oh my god, is he okay?"

A phrase used when you wish to trick another into believing that someone (fictional or otherwise) is dead, when they really are not. Derived from the conclusion of Harry Potter's 7th installment, in which the author declares in so many words,
"Hey guys, our Hero is dead!!
...jk I fooled ya'all :)"
"Hey guys, our Hero is dead!!
...jk I fooled ya'all :)"

You say LOL jk but seriously though after you say something offensive to someone or about something.
Only say this on the internet or texting. If you want to say it in real life, say "Haha. Just kidding. . but seriously though".
*It can be reduced to: LOL jk but seriously
