Since the Trudeau meme (at 4:47) might not make sense in the future, I'll explain it here: he was caught wearing blackface on numerous occasions and said he's done it "too many times to recall". The first instance that came out though was when he was dressed up as Aladdin, and this came at the same time that 6ie9ine was snitching on all his friends to get a lower jail sentence. So the joke is that 6ix9ine snitched on Trudeau.
Otherwise I hope you liked the video and feel free to comment! Also wait till the end if you want to see what the app actually looks like (the video was too long to otherwise download lol).
