A group of individuals who break into your home at night and leave a steamy pile of poop in the middle of your living room and leave. This gang of individuals are very handsome and like hot sauce. If you mess with this gang, you'll be their next victim.
Victim: "Dude someone broke into my house last night!"
To take something small, that doesn't quite qualify as a theft. Probably from the Danish "skæv" or the Dutch "scheef", both of which are pronounced similarly, meaning "askew, or not quite right'. To change an item's ownership without permission, but only something small and of little worth.
"I skeefed an apple off the neighbor's tree." "I skeefed some chips outta your bag when you looked away." "Don't skeef my chair when I go to the bathroom."
