Dunted!

This is a great word!

Especially in verb form --- I love the fact that the dull sound is part of the definition.

And I played it with 'Dex' in Scrabble. Usage: "I might not have been so soundly dunted by the paladin's mace if my half-orc had a higher dex."

Fun Fact: A dunt is the sound made by a boot to the head.
