Sphlicking
The act of trying to flick a semi moist booger that refuses to become airborne. Once it has been picked by an index finger it will stick on the thumb as it is trying to be flicked, then when it is flicked by the thumb it then sticks to index finger. This process can can go back and forth for a long period of time until it is wiped off, dried out, or simply eaten.
If you think that it was disgusting watching that chick pick her nose, you would have freaked watching her panic as she was sphlicking it back and forth while on stage.
