I find bb pretty cringe worthy, either for members or for models to use. I kind of understand why those terms get used, but it still comes across as being kind of fake and unnecessary in my book. Why not just stick to each others site names, as that seems more logical to me?
When I see guys jump into chat with a cheery, "Hi BB!", "See my PM BB", "read my PM BB", "answer my PM BB"... etc etc... my eyes roll so far back that I can just about read the label in the neck of my shirt!
In the interest of full disclosure, bb is not the only dodgy term though... baby, bebe, boo, bae, bo, beau, hun, hunny.... and a good few more all make me wince! However, if models ever call me "daddy", or refer to me as a "John" or a "Client", then I'll be in the wind... hasta la vista, tweested sistah!!!!
