Short for Working Man, it is also usually accompanied by making the symbol for the W and M with your hands, the W is made by holding the Right hand upwards with the index, middle and ring
finger all outstretched and spread apart, then the same with the left hand apart from poining it downwards.
Its used mainly to make fun of your
friends who bitch and moan all the
time like little girls about how hard they have been working
Scott: "Dude im so fucking

slave all week"
All his mates sing the chorous: "hes a Working Man, or the Working People(whilst all making the WM sign with their hands to mock him)
