What does 'dirty bit' refer to in the song The Time by the Black Eyed Peas?

Answer 1

"Dirty Bit" simply denotes the transition to sexually suggestive lyrics in their rendition of "The Time."

A "dirty bit" is also a computer term that refers to the bit that tells an operating system or OS that data is going to be written on a disk.

Answer 2

This is a remix of an older 80s song, when they say "dirty bit" it's when they break free from the original song chorus and start remixing it... Giving the song the black eyed peas sound. So dirty bit is just introducing the original remixed section of the song.
