If you're not familiar with KISS, they are the rock band with the painted faces--sort of like a loud and unsettling circus.
Famously, rumors have circulated that KISS stands for "Knights In Satan's Service." The band has consistently denied this however, rightly pointing out that the band isn't comprised of agents of evil so much as ridiculous, ridiculous men. The true story, according to Paul Stanley, is that they chose the name KISS because it "just sounded dangerous and sexy at the same time." Kissing is generally considered one of the least dangerous activities ever invented (it's right after hand washing) so we're going to question Paul Stanley's explanation here. Kissing people ain't dangerous dude. Unless they're unwilling and either a cop or a karate instructor.
Chumbawamba are a post-punk anarcho-chipotle-barely-legal-electro-something-or-other band who've been around for decades. But they never bothered anyone until 1997 when they were responsible for a song that was incredibly popular but no one anywhere will admit to liking. Statisticians are still trying to figure it out.
The official explanation for the band name is that it's a meaningless word, a combination of syllables that sort of rhyme. However, in an early interview, band member Danbert Nobacon outlined a slightly more specific origination. In a dream, while needing to take a piss, Nobacon didn't know which door to use in a public toilet because the signs said "Chumba" and "Wamba" instead of "Men" and "Women."
Huh. Gender confusion is kind of an odd thing to base your band name on, or even admit to publicly. This is basically the band name equivalent of one of those noisy conversations at a bar where you're drunkenly confiding something to a friend when the music suddenly stops playing, and the room goes quiet, and you're there yelling "I SIT DOWN WHEN I PEE." And then the stares start.
