Using my E-Authority and forum control I'm overrulling your guys's judgement of a huck.
A huck is pretty much any "drop" that you consider to be large. This can be very opinionated which is why a huck varies from person to person as far as what it is.
Ideas on how to huck and suggestions. First off, if you're going fairly slow or at a moderate speed and its to a transition then hold on for the ride, and stick your butt back over your rear wheel and make sure the front wheel doesn't go down once you go off the end. Next, if you're going fast then just hold on and make sure you're not going TOO fast.

Other ideas, include wheelie dropping which is essentially starting from little to no speed and using a pedal stroke to power yourself enough to pedal the bike off the edge of a lip (usually not more than half a stroke) as well as keep the front end up. Finally, if you're doing this huck to flat then make sure you pull your front wheel up a decent amount so you land rear wheel first, this way it eases the impact on yourself as far as how bad it feels.
