A few options to change the wording.
You have been removed from the game because the host would rather stick a rusty fork in his eye, than play with you.
Sorry, you are clearly too good to play with this group, please find one more suited to your level of perfection so that we may be able to win something.
On a scale of 1-10, the host has rated you as "I'd rather have a root canal".
You're serious??? you thought we'd play with you?
The host is setting up another game just for you. It's set for the 12th of Nextember. Please be prompt.
Your game has been cancelled...the host suggests that you and your other 3 accounts have a foursome instead.
You've been cyber dumped.
And perhaps my favorite. We're sorry, there has been an unexpected error. Please close this window and try again.
Please feel free to add to the list and perhaps we can suggest the most popular to WGT.
