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*

form of music usually created by inebriated chubby white guys at parties consisting of rapping over an instrumental track of something potentially ironic. the performer is usually operating under the idea that the more recockulous the performances the more likely he is going to get laid that night. Nostalgic references are usually encouraged, paula abdul t shirt optional
Ignoring all the sighs of reluctance from the party at Joe's loft in Chinatown, Pete was so intent on impressing Molly that he launched into his favorite nerdcore opening freestyle lyric- "My name is P to the ETE, You have got some damn sexy feet. I live in the L E S, I grew up playing N E S, Your mom's is fly it makes me wanna cry..." blah blah blah. he went home alone and rubbed one out.

Music for sheltered white kids who like the sound of hip hop but are either scared of or alienated by the subject matter and performers of actual hip hop.
Person: Hey have you heared Illmatic?
Nerd: No, rap is stupid and all it's about is guns and bling. I listen to nerdcore.
