"...You nauseate me, you disgusting, spineless, pallid little excuse for a man. I hate you. I've seen tripe in my soup that had more character than you. When we all receive our just reward, you will spend all eternity cleaning my toilets with your tongue, after which you'll have to write an essay describing your feelings about this experience, as well as discussing any new vocabulary you will have learned from my toilets. You foul little worm. For a person such as you to have testicles and a penis is such a profound waste of these lovely organs, yet I feel certain that you'd be just as much of a disgrace to the breasts and ova. Actually, the ability to have sex itself is something you don't deserve even a little bit, and as for reproducing, may Heaven itself strike your unworthy DNA from the rolls of history. May your ass-cheeks be afflicted with a red, weeping rash; may your wife continually entertain herself with syphilitic manwhores; may your car always break down in a busy intersection on a rainy day; may your armpits ache with swollen carbuncles! May flies lay their eggs in the corners of your weepy little eyes! You and your whole tribe are nothing but an infected open sore on the groin of the Universe."
No one can lay a curse as beautifully as people who've lived in the Middle East. I almost want to hide this behind a cut-tag, even though there isn't a single word in here that would get bleeped by the FCC.
