Yea i dont know anything about tennis either, but im sure racket doesnt mean an actually racket. Look at what she said Я буду первой ракоанюываывю... blah blah blah. It looks to me like its the russian word, possibly, for a femalse tennis player.

Like, when i played vollyball, i called myself 'Волиболник'. I didn't mean A vollyball, i meant, a guy who plays it.
