VOCAB BUILDER

What does attaboy mean?

Attaboy is an informal expression of enthusiastic praise or encouragement addressed to boys, men, and male animals (such as one’s dog).

Attaboy is an interjection, meaning it’s a term used to express emotion, often outside of a sentence.

The term attagirl can be used in the same way to address girls, women, and female animals.

Such terms are generally used as a way to cheer someone on, similar to saying “Great job!” or “Way to go!” For example, coaches or parents might say it to a child playing a sport after they’ve done something particularly good.

Attaboy is sometimes used as a noun referring to a statement of praise, as in The boss doesn’t usually give out attaboys like that, so he must be pretty impressed.  

Example: Attaboy, Ben! Great catch!

Where does attaboy come from?

The first records of attaboy come from the early 1900s. It was first and is primarily used in the U.S. It’s thought to be a shortened form of that’s a boy or that’s the boy, but it’s origin isn’t certain.

A similar phrase is That’s my boy! Obviously, this is said by parents, typically as a form of expressing pride in their son and something he has accomplished. Attaboy can imply this pride, but it’s primarily a way of cheering someone on, and that person doesn’t have to be the speaker’s son. Although the word boy appears inside the word, it can also refer to men—or even animals, especially dogs, as in Sit, Fido. Attaboy!
