Big thanks to ironlady and seeker4 - exactly what I was looking for! Sorry for wasting a new topic on an old one...

here is a pretty good list:
http://www.insultmonger.com/swearing/mandarin.htm

"do you like to take it doggy style?"
"你喜歡做犬交式嗎?"
ni3 xi3 huan zuo4 quan3 jiao1 shi4 ma?
literally: you like to do dog delivery style?

Gan ni liang gui gei hui ah = F**k you and your entire generation....

Ms. Chou tought me this after we cursed some drivers with the English version on the way to Taroko. 混蛋 (hun dan = bastard) almost drove us off the road and over a cliff. She said the first part in Mandarin and I emblished it with the generation bit in english...

LOL, got to love that foul mouth jien wife of mine.

Chou

Ji1bai1 膣毴(雞掰)= vagina. annoying
Ji1ba1 雞巴 = penis(usually only used in lame pornographic stories)
Jiba is a Mandarin word, while jibai is a Taiwanese word.

Ni hen ji bai eh. = you're such a cunt.

The derivations of jibai are:
Ji1wai1 機歪= annoying
Ji1che1 機車= annoying

Jiwai and jiche are less severe than jibai. In fact, most people don't find them very offensive.

lan3 pa1 懶趴= balls (the famous LP)
lan3 jiao4懶叫= penis

LP actually refers to balls, instead of penis. It can roughly be translated into "egg pod".

I don't know the romanisation system for Taiwanese, so the below you can prounce the way you would English. And the second set is the Mandarin pronounciation.

gay1sen1 jia3shian fake holy person假仙= pretentious/fake (pretending to be a saint)
dee2go1 juge pig older brother豬哥= perverted, lecherous (like a sloobering pig.)
goo2 mo1 gueimau2 turtle hair龜毛= picky, obsessive complusive (like someone trying to find fur on a turtle.)
sue2 la4 su2la4俗辣= wimp, coward(the more correct Mandarin characters would be 卒仔tsu4tzai which is "pawn" but you'd still pronounce it su la because its a Taiwanese word.)

Insulting Nouns: The first part is not as insulting as the second part.

呆子 daizi2 = dummy (this is a milder insult)
笨蛋 ben4dan4 stupid egg = idiot
醜八怪 cho3baguai4 = very ugly person
豬八戒 zhubajie4 = ugly/fat/disgusting pervert(from the character in 西遊記)
白痴 bai2chi white stupid = idiot
智障 zhi4zhang4 intelligence obstructed = retard
東西 dongxi east west = thing

混蛋 hun2dan4 mixed egg = bastard
混賬 hun6zhang4 = bastard
混球 hun2qiu2 = bastard

王八 wang2ba king eight(turtle)= man
烏龜 wugui turtle = cuckold
龜孫子 guisunzi3 turtle grandson = bastard

潑婦 pofu4 = woman who knows no restraint. I.E. Someone who just yells at things and ignores all reason.
畜生 chu4sheng = animal
賤人 jian4ren2 賤貨 jian4huo4 = prostitute, bitch. (this is the absolute worst thing you can call a woman, in my opinion. I would not someone this unless you really really hate her.)

Be creative!

I sense a popular piece of software that generates random combinations of this stuff...

My girlfriend says nobody says that....

She says they would more commonly say... 婊子.or you would say this if your girlfriend had sex with someone else... 狗男女

That's what she tells me...

FYI this topic has been merged with "Cussing Like a Native" originally from "Living in Taiwan", to provide the gentle users of Forumosa with a comprehensive and easily locatable treasury of words to get themselves beaten to a pulp by taxi drivers because of.

For your edification, a few choice Taiwanese phrases. I haven't the foggiest how best to render them phonetically, but here goes anyway.

"cong sa xiao" - cong sa/sha is the harmless Taiwanese "gan ma" (what are you doing), but when you add "xiao" in a derisively loud voice with an approximation of a drawn out Mandarin third tone, it comes off as pretty vulgar. I believe "xiao" is semen.

"juh dulan ei" - the "juh" is said with a stop that sounds vaguely like a "t". Said while angry and not particularly concerned with decorum. "lan" is of "lanjiao" and "LP" fame - and I believe "du" means to hit or strike.

So there ya go. "What the jizz are you doing?" and "This is dick/ball slapping!"

I showed my mom the cuss words that were written in hanzi and she refused to translate them, saying that people in our family don't use such words. :\

My dad likes to say gou pi a lot though....
