Yeah, knuckleball for the lack of term.

It moves in the air, and the ball does not spin or rotates.

Juninho does it well, Ronaldo too, in the vs world XI game, and a screamer in the porto game.

To hit the ball, it usually requires a straight run up to the ball, and "slice" it. It's a difficult technique, but once "kena" .. no chance for the keeper.
