An attempt to Dance using random uninhibited movements without or care for the welfare of other dancers in the vicinity. A more dangerous form of spazzla is incorporating martial arts and knocking out some other dancers. The act of falling over whist doing Spazzla, the dancer gets re-labelled as a Klutzla.
That guy was doing spazzla, and worse himself out. But at least he wasnt a Dorkla. However when he fell over, he became a Klutzla.
