Nevermind them, If they are your friends then you have bad company

Iv'e talked about naruto in public back in high school, it doesn't make you a nerd , you just like different things...I still go parties and clubs with my friends, and they all pretty much know I have a geek side, and they don't care.... If someone laughs at you for it shrug it off

Once again, if the people who were laughing were you're friends, might want to consider if they really are your friends ...
if they were serious that is

For example a friend of mine might call me that in jest, not to be taken seriously
