To run around your dwelling, pretending to be the star quarterback and throwing the winning air touchdown to your star receiver (who you may sometimes also impersonate).
Announcer (usually same person): He takes the snap, fakes left, sees Davis deep over the middle.... Releases!.... TOUCHDOWN!!!
Friend: Good throw Brees, can you score me a beer while your up Air Quarterbacking your team?
Air-Quarterback: I think I'll hold out next year for more money.
