Nintendo slider
n.— «It makes it a little easier to get right-handers out when you have more velocity, but when the velocity is lower, you throw a little more junk. Right now, my slider is working well. It looked like a Nintendo slider with the way it was breaking Wednesday.» —“Wunsch out to prove his worth” by Scott Merkin MLB.com May 6, 2004. (source: Double-Tongued Dictionary)
