A moment that has happened sometime in the past (usually the night before) and is tremendously embarrassing to even think about never mind speak about. When a 'No' moment has been recalled usually the victim will come out with a frustrated
"NOOOOOO!" groan or even a delicate "no..." mumble. 'No' moments are usually caused by alcohol and cringe-worthy social situations.
"Aww man you were totally wasted last night and you tried to pull Jessy! But she refused your sexual advances! Gutted for you!"
"Awww... NOOOOOOOOO!! ARGH"
"Was that a 'no' moment?"
"Aye, it was"
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.
