Great Topic.
In an ideal world we'd all show politeness and respect at the tables, congratulate each other and give our opponents virtual cuddles each time they won a pot.
But it's not, poker is a war people and there is no room for weakness. Don't let yourself get bullied and harrassed, pull on your flak jacket and commando trousers and fight back!
No need to lower yourself to base insults and swearwords or educate anyone. There are plenty of ways to gently tap the aquarium.
1) QUIET SARCASM
Someone outdraws you after playing horribly in a crucial pot. "nh, wp" is the short response to this.
Should you feel the need to vent further a more elaborate version would run along the lines of " I would like to congratulate you on your sterling play. It took exquisite vision to recognise that the turn AND river would both be

. I am humbled and in awe of your exceptional foresight. I foresee a wonderful future for you filled with bundles of cash, balloons and large, juicy slices of chocolate cake, stencilled with the words "I runner runnered you beeutch. You got SMOKED!"
2) THE SURREAL APPROACH
Someone getting angry and abusive at you? Confuse them with a barrage of stuff they simply cannot respond to. Some examples
Random player "You moron. If you were here now, I'd knock your teeth out"
You "Hmmm, that WOULD work, except for the fact i'm composed entirely of strawberry blancmange! HAHA SCHOOLED!"
Random player "errrr"
******
Random player "YOu cretin! How could you call WTF you suck, you total and utter FISH!"
You "I like to nibble off the chocolate edges then suck out the middle..... how do you eat YOURS young padawan!"
Random player "Errrrr"
******

3) KIPPER ALLUSIONS
No one likes being called a fish. Everyone likes being called a kipper though!
Random player "you idiot...how the hell can u call that!"
You "**SIREN*** Lower the nets, lower the nets, kipper down, kipper down" (tm belongs to leehack)
You've just had a bad beat..
"***SNIFF*** I love the smell of kippers first thing in the morning!"
4) MAKE UP NUMBERS
There's often the table theorist who likes to tell everyone exactly how to play. "J5 sooted is horrible....You called with that??? terrible play....etc etc"
Table theoristr : " Disgusting, that was a horrible call"
You: " It was a 50/50."
TT : "You had a gutshot"
You:" Yeah either I hit or I missed. 50/50.... QED"
*******
"That was terrible!!"
"You're joking!!! i was 76% to hit my draw"
"Draw?? you had nothing!"
"I was on a pair draw!"
*****
(My personal favourite, taken from a 2+2ers chat)
"Yuck you suck"
"A pair v 2 overs is a coin flip. I saw it on the ESPN poker coverage last night"
"I had AA!"
"Ya, 2 overs"
If you can suck up all the bad beats, never get steamed up enough to insult people in the chat box and conduct yourself with decorum whenever you play, kudos to you, you probably have the mental fortitude to go far. Till then, hit back with some humour.
