Here's why it's likely incorrect:
* No common idiom: There's no established idiom in English that uses the exact phrase "got up and finished five."
* Possible misinterpretations: It could be a misremembered version of a similar idiom, such as:
* "He got up and ran a five-minute mile": This would imply the person was very quick and athletic.
* "He got up and finished the last five chapters of the book": This would suggest the person was determined to complete a task.
* Context is crucial: Without more context, it's impossible to determine the exact meaning. It could be a specific phrase used in a particular group or region.
To understand the meaning, you need more information about the context in which it was used.
