Verb.
The act of waiting until someone pulls out of a good
parking spot near the store or
destination, then taking their spot as soon as they pull out; thus eliminating other people's chances to take that spot. Mostly takes place when you notice a car about to leave. Very useful in places such as
malls and department stores.
Passenger: "Hey, do you see any
spots open near WalMart?"
Driver: "No, but there's someone with their tail-lights on, let's
poach their spot."
Passenger: "Epic!"
