Well, this was in a literate group rp, in the group's map. (I'm changing names and such, for privacy sake. If you know the RP, don't talk about it. XD)
People were inviting friends to join the group, and the premise of the group is a little tricky to explain - but there are about two main factions to choose from. You could either be on the side of the "brain pride" or the "brute pride". I was/am a sort of high-"ranked" lion for the intellect pride.
We had settled into an rp, when a new person appears in the map wanting to join. This person had a typical wolfaboo/lionaboo username - somewhere along the lines of "Lionwolfy". (That name is NOT this user's actual username, but it's pretty damn close in -aboo levels.) This username should have sent flags up immediately, but the group decided that this person was literate enough to join. We had a horrible amount of Brutes at that time, so we kindly asked this person if they'd go join the Brains.
What we got was a horrible jumble of swears and calling us all "homos". And then a rant about how their character's name meant "warrior" in Swahili (or whatever language they thought it was) and how "Lionwolfy" didn't want their character to be in with a "bunch of stupid nerds". I tried to reason with "Lionwolfy" that the Brain Pride wasn't a horrible side to be on, but sadly reason does not pierce the skulls of -aboos.
The group sat there, awkwardly, letting this person go on and on like this for about five to eight minutes.
We eventually asked "Lionwolfy" to leave, and they refused for five more minutes. Then this person called us a bunch of bitchy homos and left the map.
As a group, we debated on reporting this person since we grabbed a couple of good screenies - but decided against it in the end. "Lionwolfy" ended up apologizing (kinda, but not really) and eventually joined the group. It's always awkward for the members of the group who know about this outburst to rp with "Lionwolfy". XD
