A faux to is a video that is shown as a "how to" video but in reality is someone just bragging.
Let's say there was a video on Youtube, and it was about Call of Duty. The title of the video might be "How to get a 47 knife kill streak" but in reality has no educational value and you can't ACTUALLY learn how to get that kill streak but instead is someone just saying how good they are at the game.
A: Yo look at this video called "How to get a 47 knife kill streak"
B: That's cool. But it's a faux to.
A: What's that mean?
B: Did you ACTUALLY get a "how to" lesson or was the creator bragging about their mad cod skillz?
A: No..
B: See? Faux to.
