A manc is an inhabitant of the shithole, manchester. Scientists are still unsure what species they are; possibly rodent. It is common to see them blaming scousers (liverpool) for high crime rates in the city, however it is themselves who stab old people and live off the city council. The scouse accent has been known to be the most distinguished, yet the manc tone really is white noise and ear rape according to most who are unfortunate to hear it.
To some up, they are the dried dog shit a scouser would wipe off his/her shoe before twatting one of them loud mouth cunts with that very shoe.
manc- "Oi! scouse nob ed we've won 19 titles"
scouser- "Who gives a shit your mums round the pub spending your dole and sellin her fanny for a fiver a go!"
