No, some people lose "noob" after a few days.
If I recall, the quickest was "minimum fuss" - they got a best noob award, then nobody thought of them as a noob.

Creating a new thread to show how not upset you are is classic long term noob action.

See, you're not getting angsty or upset by my arseholerly.
I declare you no longer a noob.
