1. Nerdcore is what happens to rap music or hip hop if nerds take it over with semi-professional production values.
2. The topics are always far into the nerd/geek scale, but usually presented in such an awkward way that even the geeks will refuse to watch it.

Example: Large Hadron Rap or MC Frontalot on youtube.

Every few years, on various geeky/nerdy/interweb shows, they laugh about this new nerdcore song, and it's 'actually good!' -- But it's not. It's so ghey that you actually want to punch yourself in the face for being tricked into watching it.
Nerd: Check out this new rap video. It's so cool!
Friend: WTF is this?
Nerd: It's the latest nerdcore song, the Large Hadron Rap.
Friend: You fuckin' tard, this is the gheyest thing I've seen all week. *Punches nerd in the back of the head*
