What does biff mean?
Biff is an informal English word meaning a sharp blow or punch, most often one delivered with the fist, and it works equally well as a verb meaning to hit or strike someone. It belongs to a family of expressive, onomatopoeic words — alongside whack, thump, and sock — that capture the sound and feel of impact. The word carries a light, slightly comic connotation: describing a scuffle as a few biffs suggests rough-and-tumble playfulness rather than genuine violence, which makes it a favorite in colloquial British speech and in comic-strip dialogue. Typical uses include giving someone a biff on the arm or taking a biff in a boxing match. Though never formal vocabulary, biff remains a vivid and economical way to describe a swift, forceful hit, and its punchy sound makes it instantly memorable to readers and listeners alike.
A sharp blow or punch, especially one delivered with the fist.
"He caught the ball, then took a biff from the defender for his trouble."
Almost always used in informal contexts; often appears in the phrase 'give someone a biff'.
To hit or strike someone or something with a quick, forceful blow.
"If you don't stop teasing her, she'll biff you one."
The plural is regular; it commonly refers to a series of blows exchanged in a scuffle.
"After a couple of friendly biffs on the shoulder, they headed off to the pub."
Before 'pow' and 'sock' entered comic-book panels, 'biff' was already doing the heavy lifting as English's favorite sound of a fist meeting its target.

Etymology of biff
Biff arose in the nineteenth century, first recorded around the 1840s, as an imitative or echoic formation — a word coined simply because it sounds like a blow landing. It belongs to the same tradition of onomatopoeic impact words that produced bonk, sock, and wham. No deeper root in Latin or Greek underlies it; it is purely English in origin and has no true cognates in other languages.
How biff is actually used
Biff is firmly informal and colloquial in both British and American English, carrying a mildly humorous or old-fashioned tone rather than a violent one. It suits casual narration, comic writing, and dialogue far better than serious reporting of violence.
