Nerding it up 

When someone takes something so far that it becomes nerdy. This happens in a couple of ways:

1: is when someone defines or corrects you with dictionary like precision.

2:When someone makes somethign that should be simple and makes it into something really complex by adding longgggg ass names to it

Guy : "Hey, let's go jump off that diving board"

Nerd: " Watch me do a triple backflip while rotating at 2.4 m/s at 57 degrees south of west, and land in the water creating a splash radious of exactly 3.4256 meters...."

Guys: " Uh.... nvm this guy is nerding it up, peace "
