seriously what's so funny about her videos? Penises, masterbation using chinese slang terms to describe them. Just imagine it was an english video. Say cock and then this ang moh girl says cock is a cockerel and shows a banana at the man's crotch. Nobody would even think it's funny or amusing or anything cos it's just so stupid.
You can say waxing your carrot as masterbation for example. Everyone gets it you don't need a 5 min long instructional video to describe it and the entire joke behind it is the sexual innuendo of that phrase. Maybe she's just trying to showcase to western ppl that chinese people have such phrases to related to sexual acts and body parts.

Every race has them and it would be stupid if they didn't. Don't know why some chinese fall over themselves to try to showcase they are like the western people.
