This is where a man will put his penis inside his/her anal cavity blocking off any gases trying to escape (this often works better when the reciever is ill). Once the recipient can no longer hold their fart in, the man replaces the penis with his mouth allowing the very acidic fart to spray into his mouth causing blistering and swelling at the back of the throat. Some people choose to deficate into the mouth afterwards to ensure infection. This act became popular and mainstream in the 90s.
Fancy a Samoan blowback?

Only if you promise to shit in my mouth afterward, I wouldn't mind a day off school.
