A 'no' moment is also that all important time in a story where the female main character is in mortal peril and her big strong, handsome, attractive, good looking, beautiful, courageous love interest comes upon her being injured and/or injured.
This results in him screaming, 'NOOOOOOOO!' obnoxiously and being too frozen in place to actually do something about it.
These moments are usually frowned upon by self proclaimed, 'CRITICZ' and are promply torn to pieces.
Girl 1: Oh noez, I've been stabbed, ugh...
Love Interest 1: NOOOOOOOOOOOOOOOO--
Evil Guy: >:)
Love Interest 1: --OOOOOOOOOOOOOOO!!!!
Fangurl 1: BEST NO MOMENT EVAR!
Critic 1: SHUT UP. >:V
