Requiescat in pace 

Latin for "Rest in peace".

Became instantly badass when Ezio from Assassins Creed 2 used it.

Used in gaming when killing another character or player.

Gamer: *Headshots a n00b.* "Requiescat in pace, bitch."

Requiescat in Pace 

Latin, for "Rest in Peace." You'll see the Latin word 'in' remains the same. However, it has other uses.

I am not a Latin Teacher. >/
