I don’t think he’s actually proud of his burrito. He is very aware of what he’s doing. He knows he annoys people, and he keeps doing it on purpose. It’s pretty obvious.

It would be hard to so consistently piss off people by accident for this long. This is more than likely deliberate.

Those wacky kids on the internet call it trolling 🙂

The real question is if he can actually interact with someone in a non-antisocial way. There is the outside chance that he’s socially inept, and the only way he knows how to get attention is to annoy people. I tried to bait him into a normal conversation one time to no avail. It seemed like he was not interested rather than not capable. He stays in character fairly consistently.

He does show some cracks in his armour occasionally. Usually he’s fairly unflappable, but every so often he’ll get defensive.
