It's simply a word that is used very widely on the internet nowadays; although no one knows for sure where this popular web term originated or derived from, it is likely a portmanteau of 'bro' and 'duh.'

It is treated as the internet equivalent of a scoff, usually said by one person to another when in response to something they said that is horribly overused.
