Other forms: splattered, splatters, splattering
To splatter is to scatter drops of liquid noisily over a surface. Louder and messier than a spatter.
Paint, mud and cooking fat are the usual culprits, and something splattered across a wall has arrived with force. It takes with or across. The word has given horror films the term splatter movie, meaning one that dwells on blood, and that use is entirely established. Its family is worth having together, since spatter is finer, splash is bigger, and splatter sits noisily between them.
