If I'm playing lower tables (especially freerolls
), and someone calls me out, I usually respond with "I know I'm a (their insult), that's why I'm playing at these low limits... why are you here?"
When I call myself out right back to them, it leaves them no where to go. Even if you're not a (insert insult), it's no sweat, it just takes the wind out of their sail. They may continue a time or two more, but if you joke with them, they'll stop after a while. Sometimes I've found those villains to end up telling me "good game" or something of the nature since I was able to take their ribbing.
Never let them tilt you. Don't get into a name calling match, it will only escalate the situation. And, depending on the site, you could end up in trouble with the site.
It's the same thing we're taught in life. If you let someone get to you, they will keep on.
