F.P.S.I.H
F. P. S. I. H is when your head gets so fried from playing too much first-person shooter games that you just want to take a nap and never wake up.
I got F. P. S. I. H after playing for 12 hours straight. I took a nap for 3 hours and still felt it.
My friend had F. P. S. I. H and was sleeping on the floor like a dog.
After that boss, I had F. P. S. I. H and I literally fell asleep on my keyboard.
