M-Shift
An M-Shift is when you go from bored to totally insane, and you start typing random letters on your keyboard like it's a warzone.
I was bored and started typing letters in reverse, just to see what would happen. It turned into a full-blown keyboard war.
My friend tried to type a message and ended up typing all the letters in every possible way, just because he was bored.
I had an M-Shift and typed every letter combination on my keyboard. My hands are sore and my brain is confused.
