Bad sportsmanship

it it bad sportmanship to laugh at someone when you win, and say really offensive stuff when you try to say something to defend yourself? I mean I shouldn't point names at people, but some people can act like little kids, trying to make you angry, and you're life miserable. Like this is pathetic

what are you talking about specifically?

Did you expect to find people with manners and class on the internet? If so you will be very disappointed.

Yes,

It's being an arrogant ass and a jerk with no class nobody likes players like that.

This is true.

Well specificly, some guy I apparently beat said to play me another game. After he won, saying hahahaha, and I said that it was a fluke, he then said, "like your mom!" Like really, who would win or even want to play a person thats being a jerk

Just ignore them.
