In many media, especially in children's shows, there is a character who is passive to the point of being annoying. While everyone else is wanting to go off and try a dangerous adventure, they think that maybe everybody would be better off if they just stayed put or went bowling.
This is what the character says as a weak argument against the adventure. Usually the character is blown off as being stupid, unfun, out-of-touch, and uptight. But the overall portrayal is based on whether the adventure is seen as a good thing or a bad thing. If it's the wimpy character in a group of good guys, it's bad. But if we're trying to teach an Aesop, then we were supposed to be listening to the wimpy guy.
Usually the Straight Man does this in comedies. The wacky guy wants to do something stupid, the Straight Man cautions against it, Mr. Wacky does it anyway, and Hilarity Ensues. Straight Man rolls his eyes and laments. At least for the moment.
Compare The Drag-Along, The Complainer Is Always Wrong, and I Warned You. Compare and contrast Are You Sure You Want to Do That?, which is delivered by a more confident person who is generally correct, and Actually a Good Idea, when the naysayer admits that the idea isn't terrible afterall.
