So The Who came around when all the band names seemed to be "The something", so The Who kinda poked fun at that trend.

The Hu is a Mongolian metal band (Mongolian as in Hun), and their name is phonetically the same as world famous rock band The Who.

Minor Threat has a double meaning: "Insignificant" Threat and "Youth" Threat. The song "Minor Threat - Minor Threat" really nails that point down.

Ruskaja is just blending "Ruski" and "ska" together, you can probably guess their sound. Fun fact the first time I heard "Energia" I jokingly, accidently guessed their name.

You're on the Internet so I assume you've heard the term "Circle Jerk", but a jerk is also a person, the asshole type, so "Circle Jerks" is just a play on words between those two meanings.

The Slits is an all female punk band, and the name is a reference to that.
