When a man is getting a blowjob, and right before he comes, he inserts his penis in her nostril, shoots his jizz inside her nose, so that it comes out of the other nostril. See: Neti Pot.

Inga to her girlfriend Greta: Last night I was giving Bjorn a blowjob, when all of a sudden, he pulled out and gave me a Swedish blowback! That asshole! I had to use my neti pot for an hour to get all the jizz out!
