Lunchover
Stopping for lunch in a town you don't want to spend a night in, usually to avoid family, to get together with people while traveling in between 2 towns.
We took the train from New York to Philadelphia, for a lunchover with friends, picked up a rental car and then drove to Atlantic City, successfully avoiding succumbing to familial guilt.
Lunchovers
The leftovers from dinner that you take to work for lunch.
My lunchovers today consist of Chicken Parm and a Greek salad.
