An aficionado of the Linux operating system Ubuntu; especially an individual who converts others to using Ubuntu.

Most Ubuntites get a hard-on when taking about terminal commands and new distros.
"Dan is such an Ubuntite! He pressured me into using Ubuntu and now my friggin' printer doesn't work and I feel like such a 'tard!!"
