Milk toast was a classic comic strip which featured a man who was a wimpy,pushover of a man. To call someone a milk toast is to say that they are easily persuaded!
"I'm going to gocut in front of that man in line!" "And he won't try to stop me because he is just like Milk toast!"
A teenage boy who: lacks a prominent chin, always has his shoulders slumped, is overweight, goes after girls he cannot ever have, likes poking people, makes high-pitched noises, is white, is involved in Drama, tap-dances, and smells like... sour buttered pasta.
Derived from the vintage slang Milquetoast, meaning: timid, meek, unassertive. The origin of the term is a 1924 comic character named Caspar Milquetoast created by cartoonist Harold T. Webster. A man who's depicted as a weak pushover, his name alluded to the bland food of buttered toast served in a dish of warm milk.
