look up any word, like sweetest day:
A smell and/or feeling of satisfaction in the morning after spending the previous night getting smackfaced and having sex with a random/fugly girl
Peter, sitting on the toilet, said: "Ahh, gotta love scromonus in the morning"

Dude #1: "Dude, after I screwed that fat cunt last night, I had sweet scromonus in the morning!"
Dude #2: "Hell yeah bro"
