A baseball pitch that looks like a typical fastball to you, then mindfucks you by dropping out of the strike zone as you swing, utterly humiliating you and making you look like a third-rate bushleaguer.

You need an example for this? Seriously? Fine. That thar guy on the mound sure throws a mean SPLIT-FINGERED FASTBALL. Are you happy now!?
