Get the itchy green beard mug.
Similar in meaning to chinny reckon. Used to express disbelief, always with an exaggerated motion of one hand on the chin, as though shaving/stroking an imaginary beard. It means that whatever the first speaker has said is so fanciful or impossible that another impossible thing must be true.
