A dicbic is someone who is a very big dick to the point where they make a biscuit go stale from the tone of their voice. Overall you should try to avoid a dicbic as they will ruin your life and make said life a misery and a living hell.
This is an insult that will sound so good when used, trust me try it, it rolls off the tongue
That guy at the checkout, what an absolute dicbic. His family are probably ruined
