This is so weak. Defending your position by saying that the people who disagree with you don't play tennis. That is the type of position people take when they can't think of anything substantive that isn't completely retarded.
I play tennis, and I've used it before, and I would definitely be sure to use it against you if I played you. just so you could see me laughing at you.
That´s not what I said, don´t twist my words. I said that those who have played the sport competitively, seem to have a better understanding of why it is considered as an insulting. If I played against you, you could use it as much as you like, because I already consider you a jerk, underarm serve wouldn´t change a thing.
And learn to use the multiquote-function, this many posts of aggressive bs is just weak. Dude.
