Any jager gull; especially, the Megalestris skua; -- calledalso boatswain.
a verb meaning to take a free item, or leave an item for someone else to take.
Backround: In Antarctica, it's not worth packing extra weight home, so people leave things for others to have. It's kind of like a have-a-penny-leave-a-penny, need-a-pennny-take-penny jar, except it has clothes, shoes, books, electronics, etc. A skua is actually a scavenger bird, similar to a seagull, found in Antactica.
