Much like the Guitarface, the Pokerface is used to hide emotion during poker or any other game involving cards.
Most
people are incapable of this action as they tend to snicker or jump up and down screaming "FUCK YEA I'M SO GOING TO KICK YOUR
ASS WITH THIS 'GET OUT OF JAIL
FREE CARD' WHEN IT'S MY TURN AGAIN YOU FUCKING PUSSY!"
"Woah man did you
see that? He got shot in the groin and didn'
t even blink!"
"Hmhmm, that's some pokerface he's got."
