I started riding my scooter again after about a month break, and I'm
trying to do some new tricks. I'd like to hear some original ones
that riders made up, because I'm in the process of creating my own
tricks...I already have a few:

Corn Dog-Ride off a ramp, fold your scooter up halfway and put it
above your head (it looks like a corn dog on a stick) then unfold it
and land...it is possible, I landed it a few times on a halfpipe, but
it's really hard.

Eggbeater-This can be done standing either regular or goofy. Standing
regular: Stand normal on your scooter, then let go with your right
hand and turn the bars clockwise with your left hand so you're now
facing backwards. Then do a body varial and turn the bars back the
way they were, put your right hand back on, and ride away. This is a
flatland trick, and looks really cool if you do it fast enough. It's
basically two bar turns and a body varial put together, but the
combination makes it kinda hard to complete. Goofy is the same thing,
but you stand with your right foot front first, and hold on with your
right hand, turning the bars counter-clockwise.

There's more, but I don't have much time or room to type them. Post
your original tricks, and I'll try 'em out!
