Back Worm

A Back Worm (or a BSworm) is a worm performed at the back. This is effective as it creates the biggest delay out of all the TFDB moves.

To Initiate: Either do a preparation jug or a normal jug and then shift your aim towards your back. Subsequently, do a worm by aiming the rocket down onto the ground to let it worm.

Effectiveness: When using the Back Worm, Downsides: It's only known downside is that it may redirect to another player. Otherwise, this move is highly effective, until a rocket (maybe around 15 reflects) of incredulous speed is faster than your turn rate, which makes the move useless.
 * 1) Highly effective against players who inter excessively and/or carelessly, unless he/she is a pro and does a good underestimation. Even so, you can continue to do this move until he/she has overestimated as the succession rate for this move is high.
 * 2) There is a small possibility that, when doing this move with more than 1 rocket, will enable the rocket to split into a nice form, killing multiple enemies at once.
 * 3) Especially good when there are holes in the ground. Players may suspect that the rocket will go down into the hole and create a longer delay. On the contrary, this move hardly goes downwards as the delay is more likely seen on ground, tricking your opponents.
 * 4) Good for rockets >10 Reflects as back air-blasts help to catch them faster than a 3/4 jug or a basic jug.

To Counter: Do the same or make a perfect under-estimation from the rocket's delay. Do note that back-airblasts makes the rocket accelerate to a uniform speed, so beware.
