What does cusco mean ?

There is a girl living next to me in my dormitory, she calls me cusco.
She is from Portugal, and I dont know what it means, she will not tell me.
It drives me crazy, so can someone tell me what it means ?

Actually, cusco is an abbreviation for coscuvilheiro, which means gossiper... It is usually used to mention people who are too curious...
You better watch out!
