I still think the tv peeps put him up too it, we could yell at JF because he's advertised as the best fser in the world (sometimes) but even he knows he's not, maybe Oli did it because he is trying to win some sort of competition, probably not a good game plan to inform everyone that there's an entire community of people that could rape his ass.
I will say he did over-do it, well fuck he way over-did it. But honestly just look at the way this shit was edited, I think he just wanted a better chance at winning and your attitude (as cocky as it might be) can play a huge part in competitions and shit
Look at Jeremy lynch, probably the cockiest fuck on this planet, but his attitude did add to his performance in Brits got talent
Edit: I dont like Jeremy and have never met Oli :p
