I have to agree with Team Invade when you consider we have Roboteers as young as 6 and spectators even younger that name seems inappropriate.
The rules state ( Contestants must communicate in a socially acceptable way ) and as writing is a form of communication I would say it covers names on robot.
You just wouldn't be allowed to call it that. End of. You could call it that at home or whatever, but you'd need to give it a more acceptable name for the event because it will be offensive to people. If it was an antweight it would be banned outright by the rules. In most cases, posts containing such words on this forum are removed by moderators.
