viewbag

A programmer who has an over-inflated sense of self worth, seemingly compounded by a low level of intelligence, behaving ridiculously in front of colleagues with no sense of how moronic he appears.

An insult equivalent to douchebag, used by programmers and IT professionals.

ARROGANT CODER: I'm sooo good at CSS3 and, like, wicked good at HTML5, bro. It's ridiculous.
MODEST CODER: What a viewbag.
