When you use a nunchuck to hit your face like it's your enemy. Happens when you're playing a game and you're too dumb to know when to stop.

I facenunchucked my face because I lost to my dad in a game and I was too mad to stop.

My friend facenunchucked me during a game and I got a new level of pain.

I facenunchucked my face so hard I got a new level of embarrassment and a new nickname.
