A member of a choir, or show choir, that is extremely obsessed with it. These people tend to sing non-stop, do the choir's vocal warm ups when they are bored, know every part (Soprano, Alto, Tenor, Bass, etc.) to a song, and prove that they know everyone's part by singing it all the time.
When a group of choir nerds is at a competition, or on a field trip of some sort, you can usually spot them trying to sing every song from every Disney movie or musical imaginable. They are seldom on pitch when doing so, and seem to have A.D.D. when singing. They get past a few bars of music, and then they get bored and look for another song.

Get the choir nerd mug.
The classier of the two musical groups. (Band Geeks and Choir Nerds) Choir Nerds are way smarter than band geeks, for they can play in a concert WITHOUT music, or an instrument. And even before there were bands, there were choirs! Band geeks are just too lazy to really learn the natural way of music, so they have pieces of brass/wood/strings do it for them.

Choir Nerds are usually seen with other choir nerds, and may happen to be humming, or singing selections from choir in all the differet voice ranges. Choir Nerds are (usually) comepletley obsessed with thier Choir Teaher, and add him/her on Facebook as many times as possible, before the teacher gives in. A choir nerd might also have an assortment of "Choir Nerd" t- shirts in their closet, as well as competition tees, polos, and black dressy pants and shoes. They usually take voice lessons, piano lessons and extra credit from thier director. They also seem to know the term: Hair Natzi, which makes them laugh eery time someone mentions it. And choir nerds are the only ones priveliged to say: Dipthong. Choir Nerds are simply BETTER than any Band Geek.
Choir Nerds are BORN, band geeks are MADE.

Losers that are in choir because they aren't cool enough to play an instrument. People who can't play an instrument resort to choir because they have nothing better to do in their life but mock bandgeeks because they are good enough to be able to actually PLAY an instrument rather that SUCK at singing. It takes more skill and time to play an instrument.
Bob: Hey Jill are you going to be one of the choir nerds again this year?
Jill: ha! No way, I want to be a band geek cause they are totally cool!
Bob: band geeks...
Jill: RULE!
