When you blow a big snot rocket onto somone else. And all you can say is FUCK!

or the embarassing sneeze in public where snot blows on you and everywhere around you.

Get the Snot Fuck mug.
After a man has launched his ejaculate load into some random bar whore's va-jay-jay, this is the very recognizable strand of skeet seen strewn between his knob and her over sized gash as he pulls out his spent love muscle. Typically eatin and/or slurped by said bar whore.
Dude, I picked up your mom at the bar last night and had one massive fuck snot as I pulled out of her gutter hole. She leant over and consumed the entire load of cottage cheese as I slammed my beer and B-lined for the door.
