I& #39;m not too sure about the razor joke. But Woozi did mention Dino& #39;s electric razor/shaver in a previous Going Seventeen video.

When Seungkwan was saying his closing ment as Wonwoo, one of the members sang, "Lies ~ " That was in reference to Wonwoo& #39;s solo Ideal Cut song <LIES>.

One of Coups& #39; more well-known Korean nickname is ์นํ์ค (SeungHaengSeol). It stands for "Seungcheol& #39;s (considerate) gestures make my heart flutter". So when Mingyu (as Coups) gently brushed something off of Seungkwan& #39;s (as Wonwoo) face, everyone was saying, "SeungHaengSeol!"
When everyone was gaining up on Hoshi (as Seungkwan), he said that everyone was "twelving" him. In a past If video, Seungkwan explained that the number 12 sounds like ์๋น, which means to pick a fight with someone.
