[stavros]

Being Greek, I can definitely agree. We have such phrases as "scratch your balls with a pickaxe" for when someone is telling tall tales, or "flowers on my dick and bees all around" for when you don't care. "Blatherskite" somehow pales in comparison.

I’d love a book of cool Greek insults.

[eythian]

I dunno, perhaps watch The Thick of It, then you'll get some phrases beyond a list of words that a dictionary puts on a website.
