I call a lot of girls "dude" imo that is a unisex term. I'm not so sure I can say the same about Sir though, Lol.
I believe that was one of my video game names... although I lost interest in that game a LOOONG time ago.
Although I call most irl or on mumble 'dude', Ill always refer to ya as Ahk! Hard to mistake, when players see your skin, or hear you on the mumble!!! (don't take it to heart, I have been mistaken before for female, even after players see my skin) Now... just to get the new players to see this post... hehehe... Now go forth and post more on the show yourself 2015!!!!
Kind of hard not to figure out that you are a lovely young lady if they just click on your avatar, but it is nice to meet you Sir Dude.
