A variation of the wii remote for the Nintendo Wii. Instead of holding the remote in your hand a male straps it to his penis and swings his hips to control the on screen actions.
Not very practical but fun to do when you are bored.
Friend 1: Hey dude! Wanna come over and play Wii?
Friend 2: Yeah man! I rock at playing Wii Penis!
*Both friends proceed to strap Wiimotes to their cocks and play Wii Sports.*
