A critical manager or supervisor who makes brief appearances to put on a meaningless but unpleasant display for employees to try to show they're doing their job. They swoop in, make a lot of noise, shit on everything, then fly away.
She came in and did her seagull thing yesterday. At least we won't see her again for another week or so...

Any person that eats free leftover scraps of food no matter how disgusting it is.
Those cookies have been sitting in the muster room since yesterday, but that’s no problem for Matt B, he’s a fucking 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.
Person 1: A SEAGULL!!!
Person 2: AAAAHHHH *runs away* DON'T SHIT ON MY HEAD!

A friend, lover, co-worker who finds no shame in swooping in and gobbling up your discarded food. They don’t care who’s around and who sees them do it, waste not want not is their motto. They don’t share there food, they only eat yours.
I feel bad, I can’t finish this huge sandwich.
Don’t worry, Matt will be here soon and he’s a total Seagull !!!

Rugby term, slang

A forward, usually tight forward who drifts too wide, and plays half the game at second-five. Of no use to the forward pack as a whole. Usually the domain of arrogant pricks who want to make the highlight reels.
