Now, “boi” is not your common boy. A girl can even be a “boi”. So what is a “boi” anyway? It is most commonly used to express the judgement that something is stupid, a sort of “oh no” accompanied by a pointed finger or raised eyebrows. “Boi”, however, is similar to “oof” and “yeet” in that it is also versatile; it can also be used to refer to something endearing, such as a smol boi (small guy) or a long boi (tall guy).
