When you whack off and cum in your hand, then you run up to someone, slap them in the face with your salty hand and shout "Seagulled!"

a relatively new fad among british school boys, whereby they masturbate furiously during recess, collect the jizz in their palms, find a younger unsuspecting boy and slap his face while shouting "SEAGULL!"

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.

An annoying bird that likes to hang around water and makes annoying squawking sounds. It is imperative that you stay away from these gross "flying rats" because there is a high change that they will steal your food or shit on your head. Not a nasty sexual act, just a gross bird.
