A type of person that watches and interferes with the business of others (but only selectively picking on a few individuals). A common way of doing this is through jabbing
; a beady spreads negativity and feelings of worthlessness through these jabs.
A beady thinks he knows it all (he especially thinks he has a special insight into the workings of those individuals he picks on), and his opinions are fixed on everything (however wrong).
"Beady said I should have snogged her, although he said I wouldn't have got anywhere anyway"
