Splutter is a verb that means to say something with a spitting sound, as a result of a strong emotion. It is also a noun that refers to a short explosive noise.
Our word of the day goes back to the 17th century and appears to have been imitative in origin. Here’s an example of splutter in use:
Watching the boss splutter in rage for an hour in the office like that suggested that the mistake made was a huge one. I hadn’t seen him explode like that since someone stole his stapler.
