Buster

Buster is an American surname and informal given name meaning one who busts or breaks things — originally a term for someone with notable physical strength or a knack for disrupting situations. In 19th-century American slang, calling someone Buster was both an acknowledgment of their force and an expression of easy, rough-edged affection. The name carries that same energetic, unsentimental warmth.

Buster holds the #75 spot among US pet names, with over 1,260 companions sharing it. The name has a classic American quality — it belongs to a long tradition of pet names that celebrate energy and personality over elegance. Buster tends to suit companions who are enthusiastic and physical, those who approach everything with full commitment and occasionally break things in the process. It is a name for a companion who is impossible to ignore and impossible not to love.
