Internet slang, especially popular on Reddit and Twitter/X, for a large, fluffy, impressively sized dog. A boofer isn't just big — it's the kind of enormous, lumbering, gentle-giant dog that looks like it could knock you over and then lick your face apologetically. The term emerged from the same wholesome corner of dog-loving internet culture that gave us 'doggo', 'floof', and 'chonk'. When someone posts a photo of a massive Saint Bernard or Great Dane, 'absolute boofer' is almost a mandatory comment.
That Great Pyrenees mix at the dog park was an absolute boofer — I could barely get my arms around him.
