I've long been obsessed with the late Tom Smith's use of language, lyrically of course but also in song titles:
"When My Rifle Went Sour with Preposterous Headdress"
"Fills Mouth and Cunt with 'Pathetic Route'"
"We Demand the Right to Piss in Different Colors" etc..
For PE, it's gotta be William and Philip, of course:
"Rape Day"
"Masters of the Over Violence"
"pleasure fur Frauen" too many to name
Some others that come to mind: Worth "Satan's Witches Lactate Pincer", The Rita "The Fish Woman Has Her Finger in Her Arsehole", The Grey Wolves "Unidentified Female Orifice", Gerogerigegegege "Anal Boxing", Hijokaidan "The Wreck of a Promising Youth", Prurient "The Briary (Strange Place of Death)" there are a lot of good ones. Good topic!
