Formerly, an entertainment at which each person contributed some dish to a common table; now, an excursion or pleasure party in which the members partake of a collation or repast (usually in the open air, and from food carried by themselves).
To go on a picnic, or pleasure excursion; to eat in public fashion.
When I'm home, I spend Sunday with my husband. If we're not cooking, we travel around in our camper, stop at fast-food restaurants, and picnic. We love that stuff that will harden your arteries in a hurry. Dolly Parton
People don't want to go to the dump and have a picnic, they want to go out to a beautiful place and enjoy their day. And so I think our job is to try to take the environment, take what the good Lord has given us, and expand upon it or enhance it, without destroying it. Jack Nicklaus
