SRT MOO is, in its public spaces, a "PG-13-to-soft-R" game. The general rule of thumb is that if it could fly in a non-AO-rated video game that isn't REALLY pushing that M rating the way that, say, Grand Theft Auto likes to, it's probably a safe thing to do in public.

The caveat here is of course that if someone asks you to knock it off around them, please do. It's not that deep.
