Jackinitis 

When you go into a Clash Royale slump and lose every game you play in ladder matches.

Example: When you play 2 hours of ladder matches in CR just to lose 200 trophies in the the span of 5 matches.
Person 1: I just lost 3 ladder matches in a row cuh!
Person 2: You must've got a severe case of Jackinitis!

Jackintosh 

A nickname for the Atari ST computer, after Atari Corporation's then-CEO Jack Tramiel. A reference to it being a cheaper competitor to the Apple Macintosh.

My parents were poor in the 80s and so they bought a Jackintosh for me to do homework on.
