Friday night. 'Frinight' should be used instead of saying Fri-day-night, because like saying 'mmm this cookie is cold-warm', that's really stupid. Also, Saturnight etc...
Person A: "Hey what are you doing Frinight?"
Person B: "Probably just staying in and orderin a Hot n Ready"
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."
