To pull a Brock 

To go on an expensive trip for a lengthy period of time. Once there, the 'Brock' decides to get up and leave less than a quarter of the way through in the middle of the night. The Brock's primary leaving time is within the hours of 1am to 5am. When leaving, the Brock disregards all money that they spent on the trip.

Chase: "Hey, where's Vince?"
Belle: "I don't know, why?"
Chase: "I think Vince pulled a Brock last night."
Belle: "Damnit. He did pull a Brock; that's why his grandparents were here at 3am."
