A word originating from a comic strip character in the 1920's named Casper Milquetoast. The word has come to define someone unassertive and timid.
The first time I ever heard this word was in an episode of The Gilmore Girls.
". . . You can't be a milquetoast muppet. You have to have pointy teeth and jaws that snap. The meek shall not inherit the earth!"
a timid person, a shy coward (from the old comic-strip character Casper Milquetoast)
That punk may act tough but he is just a milquetoast who wants everyone's attention.
I saw this word printed in a newspaper article describing the psyche of a hockey coach. His team had just lost an NHL series. The word was used to define the following: soft, dispassionate, non-aggressive, unbold, unwillful, non-determination and lacking strength of character.
"The coach's milquetoast attitude towards the opposition and sticking to his dogged offensive attitudes had been their unravelling."
A muppet forum poster who knows has no respect, etiquette or general knowledge of the topic he is posting about - whilst at the same time claiming "expert" knowledge.
I am very skilled so don't milquetoast me telling me to get a wing or some plane that has basic drag problems.
