thwap

Flat striking sound

Thwap is the sound of a flat object striking something—a newspaper hitting a table, a hand slapping skin, a book dropped on a desk.

The word imitates the sound itself, combining the sharpness of a slap with a heavier, more resonant quality.

As a verb, to thwap is to hit something with that characteristic sound: She thwapped him on the arm with her magazine.
