Cherry Poppin’ Daddies

Jimmy Eat World should be part of the conversation due to their acronym.

The The

Pigs Pigs Pigs Pigs Pigs Pigs Pigs. Such a pain in the arse when you have to refer to them.

Butthole Surfers have not been mentioned yet?

Hoobastank

The band öOoOoOoOoOo is a bit unwieldy.

Supposedly pronounced as "caterpillar" in whatever language you prefer.

Xavlegbmaofffassssitimiwoamndutroabcwapwaeiippohfffx

Imagine Dragons

IMO, King Gizzard and the Lizard Wizard has an awfully high good band/dumb name differential

!!! (Chk Chk Chk)

I love them as a band and the name makes sense once you know what it's representing, but it's terrible for searching or recommending to people.

Nickelback

The Beatles

Intentionally bad or unintentionally bad?

To be completely honest, I don't consider any name to be bad. 

You may say AxCx is terrible name, but once you give them a listen it exactly fits the name. Same goes for Hijokaidan, who are actually named based on one of fan's suggestion claiming that "escape staircase" suits their sound more. Party Cannon is absolutely hillarious imo, when you look at the logo and the sound. Brojob also has a name that fits their lyrical themes.

In some cases the name may come out a bit lame, but bad names? Nah. I don't consider any name bad, most of them sound either fucking epic and/or hillarious when you look at the full picture.

Come on, let musicians have some fun.

Shitfucker

Vertical Horizon

It's probably one of those ironic names, but Psychedelic Porn Crumpets always makes me die a little when I'm trying to tell people about 'em. Great band, dumb name.

I think it is a bit funny to see this question, I was in a thread just now finding out there is a band named Xavlegbmaofffassssitimiwoamndutroabcwapwaeiippohfffx And apparently is it a abbreviation for "Acidic Vaginal Liquid Explosion Generated by Mass Amounts of Filthy Fecal Fisting and Sadistic Septic Syphilic Sodomy Inside the Infected Maggot Infested Womb of a Molested Nun Dying Under the Roof of a Burning Church While a Priest Watches and Ejaculates in Immense Perverse Pleasure Over His First Fresh Fetus",

There's a band called TaintStick

Keyboard drumset fucking werewolf
