Origin Of ‘Let Her Rip’

Let’s take a closer look at two words in this phrase: “her” and “rip.”

The word “her” is sometimes used when referring to vehicles or machinery (e.g., someone might call their car a she or her). On the other hand, the word “rip” is sometimes used in connection with speed (e.g., someone might say they “ripped” through the water in their new motor boat). So much of the time, the “her” in this phrase is a vehicle, and letting that vehicle “rip” is to make it go faster.

That is how this expression is commonly used today. The oldest example I could find of it with its “go faster” meaning is from a book titled Out West, published in the year 1910:

“Git up more steam–this ain’t a funeral! Let her rip! Don’t mind the speed limit! Keep the whistle going!”

The “her” in the quote above is clearly referring to a train.

However, it should be noted that this idiom is older than the quote above. Remember, it also has the meaning of “giving someone permission to start something.” The phrase’s earliest appearance that I could find is from the newspaper Farmington Enterprise, 1809. Notice the way in which it is used:

“‘Say,’ said Tommy, ‘did I ever tell you about the circus we had at our house the other night?’ ‘No,’ said I,

settling back in my chair, ‘let her rip.’ “

So this person agreed to listen to the story, or in other words, he gave Tommy permission to talk about it. Based only on these quotes, this “giving the green light to do something” meaning is older than the “speed up” one, but I could be wrong on that. Anyways, this expression is at least over 200 years old, so that’s neat.

Example Sentences

Here are a few example sentences for this idiom. Please note that one sentence will use the expression while the other will use a synonymous phrase:
