Logan Paul's Hanging

Alright listen up, buttercup. This "joke" is saying you can't high five a Japanese person 'cause Logan Paul left someone (implied to be Japanese) hanging. This is a morbid reference to Logan Paul's infamous video where he filmed a dead body in Japan's Aokigahara forest, also known as the suicide forest. It's dark humor because it makes light of a really messed up situation. And you, my friend, are probably laughing because you're desensitized to tragedy. Sad!
