besides...what possible application could this have? annoying someone in front of you standing in a bank line?

Now there's an idea... must try that one next time. <evil grin>

an actual 'energy pull' would be redirecting an attacker's momentum in a way that they lose balance - if even only for a split second advantage. Timing could be refined to the point of not even having to touch them, or just lightly, to have this effect.
so, it's not so much an actual pull as it is just capitalizing on using their own momentum against them. the effect may look like they were 'pulled' a bit.

Nah, using the other guy's momentum is too easy. Pulling it off when the other guy is static or resisting is much more interesting, but it can be done too. Momentum is not a pre-requisite. It's just skill.
