Classics
RTFM - Read The F***ing Manual, as in the problem is simple to solve and you would have solved it if you had read the man pages before calling support.
DNT - Do Not Trust, as in the user so labelled will always answer questions evasively (or outright lie) to avoid admitting they broke something - "Did you change anything?" "Well, not today....."
A few years back, a certain IT giant opened their internal knowledge base up for customers to peruse in the hope it would get them to self-solve simpler problems. Unfortunately, the knowledge base included the entries made in call logs by their support staff and the company didn't think to sanitise the entries first, and many of the call logs were littered with RTFMs, DNTs and worse (my fave was a customer that a member of staff had described as the person "so f***ing technically-inept that she probably shouldn't be allowed to use a vibrator"!)
