A slang term which originally started with "no worries". People would often say "no fuckin' worries" to enhance the original phrase. Then, in a strange way, there was a period of
time (probably back in the
80's) when folk would transpose the first letters of certain
words. "No fuckin' worries" became "no wuckin' forries". The fourth phase of this odd phrase progression resulted in "no wuckers". It's a combination of laziness and playing with
words, and a great example of the progressive nature of colloquial speech.
Either way, it means "there
will be no problems at all". It is often suffixed by "mate".
