nasty afrin

Verb;
Whilst being fellated, the urethra is shoved rudely, upon the denouement, into the nostril of the fellator and ejaculated into.

"You get lucky with that drunk girl from the bar last night?"
"Sort of? She was blowing me down in the parking lot, but her head game was straight garbage. So, I stuck the tip in her nose and gave that goofy bitch a nasty afrin when I finally nutted."
"You should be in jail for coming up with that shit..."
