Old Japanese Phrase.

It means "Shit between your toes." and is used in context of "It can't be worse than having shit between your toes."

Was first used after the first and greatest emperor of Japan walked into the Celestial Garden, forgetting about God's dog; Amaretsu, and it's enormous shit piles.

Japanese factory owner-... Hm, yeah, I guess not.

On June 8, 2011, South Park brought attention to this pandemic of "shitty" music which is plaguing our world.

"A new music genre for the era of 2009 - 2012 (tweens)... If you have kids now, they're probably listening to it" - South Park s15e07

It's most notable list of mutated infants include Justin Beiber, Jonas Brothers, and the entire cast of Glee (except Jane Lynch).

Signs you are listening to Tween Wave music: When all you can hear is someone ripping ass into the microphone over a drumbeat. More precisely when it sounds like shit is spilling out of the speakers and puddling on the floor.
"Did you know we're living in the Tween time?... I guess it's the peroid between 2009 and 2012..." - redneck 1

"der I'd heard that." - redneck 2

"So they got this feller down at the bowling alley who gets up on stage and shits his britches.. " - 1

"what fer?" - 2

"I don't know, but he gets up there and strums a geetar and starts loadin' up his britches up like it's goin' out of style... It's like some sort of 'britches holocaust'... he calls it Tween Wave" - 1

Thanks South Park!

The escalating sound produced by a large group of tweens. At first, the sound is a light chatter. Then it grows in intensity and the frequency changes to a squeal. Eventually the incoherent ramblings of these little pricks drowns out all ambient background sound until you get a massive migraine.
After my buddies and I walked out of the movie theater we noticed a large group of tweens waiting around for mommy and daddy to come in their BMWs & Lexus to pick them up. Their tween spastics were so deafening that we started to bleed from our ears.

The dominant musical genre between the years 2009 and 2012. It combines electronic beats with vocals that are so simple anyone could sing them. To most, this genre sounds like shit. Popular tween wave artists include Rebecca Black, Justin Bieber and, debatably, brokeNCYDE.
Hey, Josephine! Have you heard the new "tween wave" song?
Yeah, it sounds like shit.

Tween case is an obnoxious mix of Pascal case and Camel case invented by tweenage girls and adopted by WoW players throughout the world. Proper Tween case involves capitalizing alternating letters, without regard for punctuation or proper grammatical rules. It may also involve the use of trendy tween acronyms and annoying amounts of exclamation points.
