Other forms: plopped, plops, plopping
To plop is to fall into liquid with a soft dull sound. Plop into the water, a plop from the pond, plopped down.
The sound is soft, round and low — a stone into a pond, a spoonful into a bowl. It also means to put something down heavily and without ceremony: plop it on the table, plopped himself into a chair. Note plop as a noun; and that the word is imitative, from the same family as plip, plap and plunk, none of which was borrowed.
