What is the stem of reverse smoking?

Anti-smoking is used to ridicule the comments of those excellent and abnormal netizens or the unexpected things that someone has done, and some disgusting operations. Reverse pumping, the famous stunt of lol anchor Sao Pig, reverse pumping. The source of reverse smoking: once PDD accidentally took the cigarette in the opposite direction during the live broadcast, put the lighted end of the cigarette in his mouth and fired a bunch of 666. As a result, the stem that was pumped backwards appeared. Then the ridicule of netizens became the phrase "pdd comes first, another day, and the anti-smoking day is immortal." Recently, I was ridiculed at the Tucao Conference. Netizens used this stalk to ridicule some powerful netizens. The anchor scene is 1. Half cappuccino 2. Fu sang Desert Camel 3. Liu Bo's various funny clips 4. PDD smokes in the opposite direction. Take the big brother and neighbors to scold each other (why shout loudly? )
