Everyone knows what cool dude means by now.

Wait, they changed it back to cool dude?

That's helpful at least, I was under the impression it was still five pound symbols.

Most insults are filtered for having been misused in the past rather than for being inappropiate.

The above well tell me whether or not it's pounds or cool dude.

But yeah, those situations can be uncomfortable. I find the best option in those cases is to just try to leave the vicinity as quickly as possible. If your stuck there, though, then I have no clue how to avoid it.

EDIT: Yeah, it's pounds, not cool dude. Cool dude is the i word, which I'd say with a zero but then B6 would pop up and I'd have bold do not bypass the filter text.
