One-Liner That Shuts Table Coaches Up...

[InternetPokerPro]

Anyone insisting and gambling and having a good time please leave the table immediately . . . I only want action when you have the nuts against me. I will be reporting any gambler directly to support.

this was in another thread a while ago...

"I will [censored] your girlfriend in the ass"

[TruePoker CEO]

Don't bang on the side of the boat....

However, as you limited your scope to one-line, citing Paty's limited chat, I do feel constrained to point out that the chat facility at Truepoker allows for much better chat,, and directly on the table, than does Party.

lil told me this a LOOOOONG time ago and I love it:

Shut up... I/he/she is/are counting your chips and it's hard to do with all that talking

"If you want better players fck off to the 15-30"

It usually works.

Unless of course you're playing 15-30, in which case you'd just sound silly.

I personally like....

"Just STFU"
"Don't tap the glass foo"
"Pokar is easy!"

My all time favorite...

"I bent your mother over a barrell"

How about "smart pros charge for lessons". May take the average table coach a while to figure out whether you are giving a lesson, insulting them, or complementing them by implying they are a pro. While they work it out maybe they will shut up.

"Yeah, I wish these guys would play better so I actually have a chance to win."

Though it works sometimes, other times the guy actually agrees with my sarcastic statement.

The last table coach i encountered offered me some advice, as he was doing to everyone else. He said something to effect that i had bad habits. I informed him that me chasing may have been a bad habit, but him informing me of this was surely a worse habit. Another decent player said "i agree" and table coach shut up for the rest of the evening. The only problem is this line is hard to take if his comments are being directed towards another player.
Perhaps: "being a table coach is not a smart play either, in the long run"

Sometimes in desperation, especially when someone is actively berating and making it unfun for the person willingly losing their money, I type in a single letter and hit return in rapid succession back and forth until I've gotten the offending speech off the chat screen.
