Tomboy

"ボーイッシュ" (boyish) is a Japanese term derived from the English word "boyish," which has the same meaning as the word "tomboy" in English.

Both "boyish" and "tomboy" are terms used to describe a girl, typically a young one, who behaves, dresses, or participates in activities traditionally associated with boys. Tomboys often prefer activities like sports, roughhousing, or playing with traditionally "boyish" toys. It's important to note that being a tomboy doesn't necessarily mean a girl identifies as a boy; it simply means she doesn't conform to stereotypical feminine behaviors or interests.
