Slightly off topic but if SereneProdigy can source some classy modern invective I feel obliged to give an example of it's proud Rabelaisian ancestry:
...but did injure them most outrageously, calling them pratling gablers, licorous gluttons, freckled bittors, mangy rascals, shiteabed scoundrels, drunken roysterers, sly knaves, drowsy loiterers, slapsauce fellows, slabberdegullion druggles, lubbardly louts, cozening foxes, ruffian rogues, paultry customers, sycophant-varlets, drawlatch hoydons, flouting milksops, jeering companions, staring clowns, forlorn snakes, ninnie lobcocks, scurvy sneaksbies, fondling fops, base loons, saucy coxcombs, idle lusks, scoffing braggards, noddy meacocks, blockish grutnols, doddi-poljolt-heads, jobbernol goosecaps, foolish loggerheads, flutch calf-lollies, grouthead gnat-snappers, lob-dotterels, gaping changelings, codshead loobies, woodcock slangams, ninnie-hammer fly-catchers, noddiepeak simpletons, turdy-gut shitten shepherds, and other such like defamatory epithets.
(Francois Rabelais c1535)
Now I would find it hard to recover from that broadside.
Up yur nose with a rubber hose!
At home we say Téigh trasna ort féin which means Go Fuck Yourself basically hehe
My favorite way is to tell someone, " And I hope that you too have a sparkling day"
or, "And a Merry Christmas to you too, Tiny Tim,"
"When its too kinky for everybody else, its just gettin' good for me."
(Kinky Freedman)
Slightly off subject but three phrases, ''fuck you'', ''fuck off'', and, ''you know'' make me crazy. Typically these are seemingly used when the person speaking cannot actually formulate a thought into meaningful words.
My favorite is "Suck my left one" and walk away!
Equal opportunity insults:
'I hope your tiny pecker falls off douchebag!'
'May your snatch dry up and crack!'
