well lets see, would you like to be labelled a ''nerd''
''They typically appear either to lack confidence or to be indifferent or oblivious to the negative perceptions held of them by others, with the result that they become frequent objects of scorn, ridicule, bullying, and social isolation. Some nerds show a pronounced interest in subjects which others tend to find dull or boring, or just simply too complex and difficult to comprehend, or overly mature for their age, especially topics related to science, mathematics and technology.''

WTF mate. It was meant as a self deprecating humour. I've been called much worse in my life in less than humorous situations. Since you seem to like quoting Wikipedia here is a definition of 'self deprecating' for you.
Self-deprecation is the act of belittling or undervaluing oneself. It can be used in humor and tension release.
