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."
