Torvalds' Witness

"Do you have a moment to talk about our lord and savior Linux?"

An elitist Linux nerd who preaches that Linux is the one true greatest operating system, and sees all non-believers as inferior to themselves.

Derived from Jehovah's Witness.

No, I will not use Linux, you damn Torvalds' Witnesses!

Jesus. That's the last time I'm ever using Stack Exchange!
