Agreed. Warning for this at all without at the very least a verbal sets a weird precedent. Dirty jokes haven't ever really been a big deal as long as they don't cross a line.

We're not warning every time someone says suck my dick to someone directly, idk man

 
I personally think that the line was crossed when the message was directed at a person who wasn't there to consent/be in on the joke. 

It just sets a bad precedent. All it would take is one misunderstanding for a message like that to create much deeper problems than it should (this thread being one of the less harmful examples of that). I would really not like to see messages like that directed at people who either aren't interested or aren't present. 

Once again, it's clear that in this specific context, the message was not malicious. Had I been the staff member there at the time, I would probably have stuck to a verbal warning, but given how far this issue has gone, I have reconsidered my stance. It's now pretty clear to me how easily this type of message can be mistaken for something as serious as sexual harassment, and because of that, I think this type of language should be taken a bit more seriously.

EDIT: I was informed that d33r was present at the time the joke was made. While my above opinion stands, I think (pending a non-negative response from d33r) this would be fine to be bumped down to a verbal.
