Unless of course you happen to be the person in the video, in which case (it is easy to construe) "I'm really shit, but not as shit as the person I have just videoed and taken the piss out of". Unfortunately, in today's digital age, so many people still don't understand that once they press send, they are no longer in control of 'context' or 'statement' or 'public consumption' and are therefore open to exactly this.
I'm sure he didn't think. But that isn't a defence for any of us.
And I say this as someone who habitually takes the piss out of everything and the more politically incorrect the funnier. But I am increasingly nervous (and therefore conscious) of the potential consequences.
