Sack-blocked

When a hacky sack is snatched by another player just as it is about to come into contact with your foot or other body part. This feeling leads to a loss of balance due to the predicted force of the hacky sack on your foot or other body part actually not arriving.

Jack plays hacky sack quietly by himself

Max snatches the hacky sack right out of the air just before Jack is about to successfully complete his jester.

Max: SACK-BLOCKED!!!!
