Twins Outside Slants is a 5 on 5 flag football play that is executed out of the Twins flag football formation.
The 2 wide receivers (A, B) line up to the far left or right, depending if the formation is stacked to the left or right. They should be near the sideline and somewhat close together (this is the same for all Twins formations). The quarterback (Q) is under center (C) and the running back (R) is lined up on the opposite side from where the wide outs are lined up, 3-4 yards deep.
Primarily when the ball is snapped, the quarterback executes a quick pass to Wide receiver (B) who is running a quick slant across the middle.
Secondary option is to pump fake to B while giving Player (A) time to run a deeper slant (or post). Players (R) & (C) are short dump off options, should the play break down. Player (C) should hesitate then come along the line of scrimmage and into the area vacated by (A) & (B). Player (R) should work the opposite side of the formation in the area just in front of where the defensive back would normally line up.
Optionally this play (as with most twins formations) can be called as a hand-off or a draw. This occurs exactly as explained in the previous play, Twins Outs
