JK 47 

In context, JK 47 means the same thing as jk, or, "Just kidding". Although, it is more of an intense jk as it bears a wordy resemblance to the gun, AK 47.

"Man, I totally just robbed your house!"
"WHAT?"
"JK 47, dude."

The ak-47 of "just kidding" used to express the ultimate form of non-seriousness. A variant on jk, used in roughly the same manner, however with more emphasis on the joking aspects.

Nick: Dustyn, I totally banged your mom last night, and it was super stinky.
Dustyn: Dude, not cool.
Nick: jk-47! It wasn't stinky!

Automatic lyricist. Spits like an automatic from the grill to the mic. Also means one bad muthafucka. More deadly then an AK cuz its a JK. Defines life and fashion. Ultimate supreme being.

"I wouldnt even fuck with the JK-47, thats to much power for me, to much skill involved there."

When you intend to do harm with a statement or phrase, but play it off like you were kidding. Is not used when talking to the person emotional harm was done too.
