Girls that play mw2 and sexist people...Please?

I play mw2 and I don't bug anyone...mostly S&D and today I got harassed BADLY...from the moment a few teenage guys saw my clan tag as "G!RL" they all got riot shields and trapped me in corners and let the other team kill me and I couldn't do anything about it...then they kept making fun of me and kept saying to everyone "Nobody kill each other- JUST GO FOR THE GIRL!" and I kept dying every round. Then they made fun of my score and said I should be in the kitchen and then said "ANY ONE WITH A SCORE BELOW (my psn) NEEDS TOO BACK OUT TO MAKE HER LOOK BAD" and they kept harassing me over the mic...one dude kept sending me rude messages and "smart a**" messages trying too piss me off and he is STILL doing it- this was about an hour ago...Is there like anything I can do? Have you seen this sexism before on x-box or ps3? Thanks...
