means Waste Of Pussy
a girl can be a W.O.P.
or what she does can be a W.O.P.
heres just a few examples:
the hot chick in a movie gets killed you say "man what a waste of pussy!"
or a girl thats just so messed up mentally and/or emotionally that shes undateable, shes a W.O.P.
when you see hot chick with an ugly guy (asian girls for example) thats a W.O.P.
still means with out papers,
this was a problem for many italians when they were immigrating from the homeland, they didn't bring any papers with them, i don't know if my greatgradfather had this problem but it is one that many of our ancestors faced it's just directed towards the italian population, it can be used as a demeaning term to put down someone that is italian when you yourself are not, my friend calls me a w.o.p all the time and i call him a mic cause he's irish.
scott, "c'mon you stupid fucking w.o.p!"
me, "go eat a potato and chase it with a beer you fucking mic!"
(to this present day we are still friends and there are no hard feelings between the two of us or our families)
with out papers dirty hairy italian people
