I've seen a reverse kong before. It's not useful, it's just showy, hahaha.
It's a bit like jumping 180 over the obstacle, then applying your hands to the obstacle and pushing...backwards? I guess?
Not entirely sure the technique itself; haven't ever done it, just seen a friend do it, as well as variations of it.
I mean, just a straight-forward reverse kong, not coming out of something.
And seriously, there's no need for the excessive amount of emoticons, it makes your posts funny-lookin'.
