@Indy: I presume that your question is infact a prompt as you should already know the answer to your quandry according to the All Saying Id. It could be tough with the filter on but I'll try and spell it out for you.
There are regional differences regarding the perceived severety of various vulgarities. Needless to say they will also predominantly be words concerning genetalia, intercourse, excrement or some such topic with graphic and taboo overtones. The make up of the words is also important and they generally share common structures. It is here where the "celtic" chappies sneak in. A good bad word will have a strong, sharp shock so to speak. A seethingly sharp "f" deep "u" and rock solid "k" is an obvious classic. The slimey, piercing and sharp combo of an sh coupled with the i and t is a good'un too. Grom's fave, and I am 100% with him in voting vor this as the numero uno bad lad, is the strong yet sharp "c", the deepest of deep "un's" topped off with yet another sharp but strong consonants, the "T". Not to mention what the word actually represents.
Now! What happens to the eff word if we supplant the depth of a "u" with a soft "e"? Yes folks, a seemingly miraculuous downgrading of the word to a rather elf like frivolity; Feck! This charming little celt recieves broad grins even when broadcast during pre-watershed hours. Imagine the uproar if Fr. Jack was more fond of the "u". Drink! Girls! ****!?. Please, not infornt of the children, you may take the mick out of the Catholics by all means but please mind your p's ad q's, or u's and e's to be exact. (Likewise stick an "e" at the end of sh1t and you soften both the vowel and consonant to an acceptable (ish) point.)
Of course, my dear friend the bollock is even given an "i" when pronounced back in Dublin thus endeering itself to American tourists when used in the phrase "get up out 'o dat ya little bolix".
If you wish to investigate the thesis further refer to the works of one Dr. U. Id, B.A, M.A., PhD, FU2., published by Drinks Press.
