I cast "Baconstorm!"
I guess I've just never seen this problem at the table. Some players are a bit more, umm, expressive in their RP that othersHow many chances do you give someone though? I'm not saying it has to be Shakespeare here, but, there should be at least enough of a personality in the character to delineate the character's gender, species and general culture.
Heck, I don't really care if it's done badly. I care that it's there AT ALL. There's a million ways to play a character, and probably most of them are not exactly going to win an Oscar. I'm groovy with that. All I want is the player to put in enough of an effort that no one at the table is ever surprised by basic facts about the character that should be pretty obvious from casual observation.
I really don't think that's too much to ask in a role playing game. If your character is physically strong, I expect that to affect your portrayal of the character, just as if the character is physically weak. If the character is female, there are a million and one ways to bring that to the table, some great, some, not so much.
I'm just asking for one.

But at that point its seems they're either the type to just sit on the sidelines doing more watching than playing (that's where I used to be!); or else they're the type to to play the game more as a purely tactics game. Either way, it still doesn't bother me much, as long as they're enjoying themselves and not ruining it for others.
Of course, in my experience, players are few and far between so I can't be too terribly picky who I choose to play with.

A player who's creepy, smells bad, or is an offensive jackass? No.
A player who's unable to RP, or not truly interested in RP? Meh, I think I could work with that.
