A portmanteau of simultaneous and listen, a simulisten occurs when two or more people in an IRC channel, on Facebook, or on a message board decide to listen to an album simultaneously. Usually accompanied by unanimous praise and multiple users quoting the lyrics.
Adam: dude bro wanna simulisten that new eminem shit
Billy: shit yeah bro gimme a sec to queue it up
Adam: okay ready, 3 2 1 GO
Billy: fuck yeah Charlie: what are you two idiots doing
Adam: we're simulistening the new eminem joint, you in?
Back when people watched television with a digital cable box, you might've noticed that two or more channels broadcast the same exact thing. They might not all be in sync though, and the 'carbon copies' are often worse in quality. This is strictly known as simulcasting.
When I was a kid, I used to find it mildly intriguing that channels 26, 232, 234, and 556 all broadcasted the exact same content. Didn't know these were called simulcasts until now.
Japanese Anime that is recorded as broadcast, i.e., nudity and flashing images are censored with mosaics. It is the opposite of "uncut" which is uncensored content made for Western countries.
