the ultra death-skank of uber-doom (or UDSUD) is a technique of skanking invented by a highschooler named nate used to skank in mosh pits withouth hXc dancing.

can also be used to smash people's balls in or give them a dead leg so you can grab whatever you are trying to get from them (ex: bag of weed) and yell YOINK and then run away really fast
dude! nate just used the ultra death-skank of uber-doom on ezra again because i think he said something about his sister and had to get an unfair advantage to run away because of his stoner asthma!
