When you're playing a video game, normally a handheld one, and your pinky finger goes numb, cold and stiff. Caused by the position of your hand cutting off circulation to the afflicted finger.
A good remedy is putting the finger near something warm, but be careful.
Alan and Bob were playing Mario Kart DS. Bob was in the lead, but then he got a gamer pinky and spun out, then Alan passed him.
