You were so wasteds you almost got in a fight with a guy twice your size! You wouldn't stop hitting on his girlfriend! You got damnesia, because I was like DAMN when I saw that!!
When a situation follows with: Damn! That didn't happen or damn! I don't remember that; usually after copious amounts of alcohol, due to having done something regrettable that someone reminds you of the day after, that you don't remember.
