one who types obnoxiously loud or with great force
The thundertyper sitting behind me at the coffee shop needs to take out his anger on something other than his laptop.
Typing extremely loudly on a keyboard. usually when angry.

When you're on skype/videocall and you can hear someone typing furiously on the other end
