CR7 is the long established nickname for Portuguese footballer Cristiano Ronaldo, combining his initials with his famous number seven shirt. The phrase un poco mas is everyday Spanish for a little bit more, which is why Spanish speaking fans and editors quickly adopted short Ronaldo related clips like this as reaction audio. It circulates on soundboards and in football, fitness and gaming edits, where the short running time makes it easy to loop, layer over a replay, or drop in at the exact moment someone asks for more.
