B-anter 

Internet message board and forum style. It's followers are distinguishable from the more common 'banter' brigade by virtue of the fact that their ramblings are far more intelligent, if forthrightly expressed, on a whole host of subjects: normally rubbish ones. Text speak is strictly outlawed, as is being generally stupid. It's the hyphen that does it; and it works for all manner of things. E.G. What shall we have for d-inner tonight? I've just f-arted. etc.

B-anter was great last night wasn't it?

Did you see those numpties on banter? Give me b-anter any day.
