Smoking a bong through your dickhole. (The smoke comes out your ass, if you're experienced.)
Yulning hurts worse than Lars's Mom, but it's the only way I can get my fix.
Covering your crabs with gonorrhea ooze, sticking them up a corpse's ass, pulling them out, putting them back in the dead woman's pussy, licking them up, vomiting them out, and having a sex slave eat them and chew them up and spit them back into your mouth, i.e. the most disgusting act humanly imaginable.
Klurg is so fucking vile I can not even think of an example to express my disgust.
