A phrase used when one either: (1) Does not know what is going on, (2) does not know what just happened, (3) does not know the answer to a question, (4) or simply would like to break the silence.

Usually, when said phrase is used, it is followed by a near-endless spree of other quotes such as:

1.) Psh, I don't even know.
2.) Aw hail naw.
3.) Aw hail naw, cracka.
4.) Mmm hmmmm!

The phrase "I don't even know" is best used in the classic "I don't even know" speaking tone, which may only be properly "voiced" by either a colossal, Japanese monster, a small cat/kitten, or a constantly hyper-active younger brother.
"Matt, why aren't you talking?"

This clever phrase was invented by the bright, young man, Chris Allen. He patented the phrase on July 15, 2007. The phrase, "I don't even know," is quite an unique expression. It can be used as a extreme adjective to describe the undescribable, or it can be used to express thoughts of confusion. It can also be used as a verbal space filler. This phrase will go down as one of the best phrases in all of phraseology history.
"Man, that girl is as ugly as... i don't even know."

"What's going on tonight, bro?"
"I don't even know, man."

((When in a conversation and an awkward silence comes up))
"Yeah, well, I dont even know."

Get the Liquor? I don't even know her! mug.
This phrase is tagged to the end of one's speech in order to reveal an innuendo or undertone. It is expressed with a wide-eyed expression and a tone of confusion. It is often synonymous with "That's what she said".

Unlike "That's what she said", it is proper for one to add this phrase to the end of his/her own speech, as well as for others to do the honor for him/her.
