Some players truly deserve all the accolades they receive, and are well liked and received by the community. Other players however are completely worthy of all the vitriol and disrespect that can be directed at them. My suggestion is thus: A 4th attack option with no EXP gain, no money gain, and a hospital stay similar to a Leslie attack. I would have this option split based on your characters sex, the options would be "teabagging" or "clam dipping". This would be a non-stealth attack. If you chose this option, your intended victim would know who you were.
As an additional thought, you could have merits for those people who have been especially victimized by these attacks "dipped more than Earl Gray" comes to mind readily. I realize this is a fairly juvenile suggestion, but I think some people take this game far too seriously. Obviously, you don't have to use the suggested terms, but I'm sure you could come up with some other equally demeaning terminology with a bit less of an adult theme.
Cheers!
