A term used for endearment. What a girlfriend calls her boyfriend. A girl will call you wonderboy because she cares about you & she believes you can do anthing. You may be flawed, but she still sees you as her hero.
Basically it means someone who is inanely stupid , usually applied to the type of individual who is slow witted but unsuccessfully attempts to assume perceived intelligence and wit by making grossly inane,exagerated , and ludicrously inaccurate comments.
The hostile reaction of the press to people who choose not to observe national anthems reveals that far from being educational and informative they arevperceived as a bunch of domeless wonderboys.
