An visually confusing attack where the defender must guess which direction to hold in order to block correctly. Typically a jumping attack (often j. mk or j. short) with a wide active hitbox performed as the opponent is waking up. Ground cross-ups also exist but tend to be less-ambiguous since they aren't as difficult to react to.

Can be abbreviated as xup

Although these pictures appear identical, they are different.
In the first picture, Ryu must hold left to block the crossup successfully
In the second picture, Ryu must hold right to block the crossup successfully

Thanks to nohoho for finding these pictures.
