There are 2 definitions of this word:

1.) -a band whose members include Little Jimmy Urine(lead singer), Kitty(drummer), Steve, Righ?(guitarist), Lynn Z(bassist), and formerly Vanessa Y.T.(bassist). They sound like punk rock, techno, and rap all mixed together and describe their music as "industrial jungle pussy punk".
as if their parental advisory-labeled lyrics aren't controversial yet wicked crazy-awesome enough, their shows have involved Jimmy setting his dick on fire, drinking his own pee, making out with girls and guys in the crowd, ect. The cds you will most likely be able to find are "You'll Rebel to Anything(As Long as it's not Challenging)", Frankenstein Girls will Seem Strangly Sexy", and "Tight". In my opinion, THEY FUCKIN ROCK!!!

2.) -the act of masturbating (which is probably how the band got their name.)
I practice a mindlessly self indulgent mindless self indulgence. I have mindlessly self indulged many times before. In fact, I mindlessly self indulged just last night. I will mindlessly self indulge tommorrow, too, because I mindlessly self indulgently mindlessly self indulge everyday. I am mindlessly self indulging right now over my favorite band, Mindless Self Indulgence.
