a man who has a shrew penis

A male with a penis so small or gives off small penis energy.

emo-penis (german: emo-penis) is a definition for people with dyed hair and piercings.

The attitude common in cranks and tech nerds who try to avoid being “sheeple” by creating unnecessary complexity. This includes attemps at “sticking it to the man” by avoiding elegant, well honed solutions. They have the relentless urge to muck around default settings to show how 1337 they are.
Good examples are installing pfsense instead buying an off the shelf router that’s simpler. Using the command line (for non repetetive tasks) even though the GUI takes the same time.
