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".
Term used oftenly in the Plano, Texas area to describe the rivalry between the Plano Wildcats and the Plano West Wolves. Those who favor Plano Wildcats use this term instead of saying "Fuck West" they say "WuckFest" or "Wuck Fest"
Person A: "Hey, are you going to the Plano football game tonight? its Plano vs. Plano West."
