What is the meaning of "Dad fetch it" from tom sawyer?

Question

i am from china.thanks

Answer 1

Tom uses "Dad fetch it!" as an exclamation of annoyance. Literally, "Dad fetch it" means "Father go get it." In Tom Sawyer,  though, the phrase has no literal meaning but would be similar to saying "d**n it!"

Answer 2

It's an expression of mild dismay at a situation, similar in meaning and intensity to "d**n it." Phrases like it were popularized by people's efforts not to say "God d**n it" (which would be taking the Lord's name in vain), using phrases like 'gol d**n it,' 'dad gum it,' 'gosh darn it,' and so on.
