A manager who flies in out of the blue making a lot of noise then craps all over everything and flies off again.
A seagull manager is an absent / occasional manager who wants to be seen to be doing something useful but realy has no contribution. To make up for this they turn up from time to time and flap around making sure they tell eveyone what a wonderful job they're doing while at the same time dengrating or undermining the real work being done by their happless underlings.
