Reversed snot shot

The act of ejaculating so hard at the back of a woman's throat that semen comes out of her nostrils. She then has the option to blow the semen out or sniff it back into her mouth, at her preference. This is the reversed version of the regular snot shot, where a man ejaculates directly into a woman's nostril.

"Hey Jean Claude, how was your date last night?"
"Dude, you won't believe this, she blow me so hard I gave her a reversed snot shot!"
"Wicked, Jean Claude."
