Origin Of ‘Let Her Rip’

Who is the “her” in this phrase and what is she “ripping”? Is it a woman tearing a piece of paper in half? Let’s take a closer look at these two words and see what they mean within the context of this expression.

The word “her” is sometimes used in connection with 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 relation to speed (e.g., someone might say they ripped through the water in their new motor boat). So basically, the word “her” in this phrase generally refers to a vehicle, and the word “rip” means to make said vehicle go faster.

Now, then, how old is this phrase? 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” referenced in the quote is a train.

What about the idiom with its other meaning, that is, ” to give someone permission to do something”? The earliest I could find it used in such a way is from the newspaper Farmington Enterprise, 1809:

“‘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.’ “

In summary, this phrase is at least over 200 years old! Neat.
