An emotionally blackmailing and often disturbing charity advert that infers a negative moral standing on the viewer if they do not subscribe to them. Usually accompanied by a sanctimonious, platitudinous voice-over and distressing music.

i.e. if you don't give us money, we're showing you is your fault and you are a uncaring/neglectful/heartless cunt.
Dave watched NCIS as always, but in the first commercial break there was a cuntermercial that made him feel terrible for having his comfy sofa and nice girlfriend.

He nearly pledged the 3 bucks a month but the pizza turned up.
