netbragging 

the act of going to a social networking website and, instead of networking, you only write about yourself, what you think, what you have said, what you have done, what you like, what you eat, what you think of politics, what you think of music ... because it's all about you in the end, isn't it.

Going to Facebook and netbragging, "There are three things that are important in my life ... me, me, and me," or "I'm sitting here thinking about me and what I'm going to do next" or "Why hasn't anyone asked about me?" or "My life is blessed ... because I say so" or "I just got a puppy!" (the last one an obvious ploy for people to ask about you)

nerdbragging 

When someone brags about being a nerd, or shows off their nerdy knowledge to someone who isn't nerdy.

Emily was nerdbragging about Tolkien, the other day, it was so confusing.

Nutbagging 

The act of getting repeatedly punched in the nuts whilst being fellated.

She gave me a nutbagging the other night, hurt like hell. But I liked it!

netbanging

Gang activity on the Internet, recruiting, taunting rival gangs, posting information.

Since they started netbanging, we've had more gangs and more crime in this city.
