What it means
A wallop is a proper hefty hit, or the act of dishing one out. Not a little tap, more the kind that makes everyone nearby go oof. You’ll hear it for punches, a ball to the face, or anything that lands hard. It also works for shocks and bad news that hit you in the chest a bit.

Where it comes from
Wallop goes back to Middle English and first turned up as a word for the pounding noise or motion of galloping. Chaucer uses it that way. From there it drifted naturally into meaning a heavy blow or forceful impact, which fits the sound of it perfectly. It’s one of those old thumpy English words that still earns its keep.
