K18 is a term synonymous with user error, usually used to prevent yourself from looking like a complete jackass.

K18 stands for "Keyboard 18" which is an error code for an error which occurs roughly 18 inches away from the keyboard. You can almost always redirect the blame to the device you are on by listing an "error code"

Doesn't have to be strictly on an electronic device, can be used for any general fuck up.
Kate: Hey, you charged me $12.20 for this?! The label reads out $6.

Josh: Sorry! K18, must've scanned the item twice; this error happens all the time!
