The phrase "out up on" is a combination of three independent words that could each have separate meanings. However, when used together, it does not have a specific, widely recognized definition in the English language. As such, it is not listed in dictionaries as a stand-alone phrase.
Individually, the word "out" often denotes something moving away or departing from a particular place, or can refer to an external or outward direction. It can also mean to expose or reveal something, or to no longer hide a secret.
Meanwhile, "up" can refer to a higher position or upward direction, or can be used to indicate an added or increased amount of something.
Finally, "on" typically denotes a position above or in contact with something, or can indicate progression or continuation.
However, when these words are combined as "out up on," their specific meanings do not correspond to any established concept or phrase recognition. It is possible that this combination of words may have some regional or cultural significance or could be used as a colloquial expression within a specific domain, but it does not have a widely accepted or defined meaning in standard English language usage.
