Das it Mane 

Das it Mane is a phrase often used on a Facebook page titled satan which may have it origins in das it, which is pHispanic] slang for the words "that is it" The word "Mane" in Das it mane most likely is an intentionally pcute] misspelling of man. The phrase probably originated from the admins of the facebook page, but nobody has bothered to verify this because nobody rele gives a rat's ass about das it mane anyhow. I don't even know why I myself bother to writing about it. I must be bored.

man one: "das it mane"
man two: *fails to notice man one talking to him as he is singing along to Willie nelson's worst ever song which is playing almost to quietly to hear on the Walmart stereo system.*
