Resolved Question

when i was in Germany as a youth i tried to improve my swearing capacity by reading an making up words like lech mich am glocken ende . I dont think that is spelt right but its thge thourght that counts.

Firstly, and in general, because Germans do not have the same habit of playing with words or creating new words on the fly.

Secondly, and in this case in particular, Glocken and Ende when put together mean nothing to a German. Their rough equivalent, I guess, would be Eichel. How would an English person react to a made up curse like this:
"You are a complete acorn".

It just doesn't work to take an English idiom and translate it literally into German.

Even "Lech mir im Arsch" - does not translate exactly. in German, it's meaning is not so strong, it is more permissible in mixed society than it's literal translation would be in English. So a better translation would be "Eat my shorts" as this has the same meaning, power, and swear-wordiness as LmiA.

Also, you should put some thought into getting your normal English correcter, than mooching in bad words in forrun, iinnit tho'?
