"IT'S ALL LATIN TO ME!"
 
This quote means it's all gibberish.. Something is not understood and this quote is used to show a subject does not make sense. Also derived from the quote "It's all Greek to me." Take this morning for example, with Dr. Preston, he was talking about a task with a subject I am not familiar with, I thought to my self... "This is all gibberish to me," lost in what he was talking about, I was thinking, "Summer was over to soon."  The point is this quote is a figure of speech when one does not understand something.
