1. tv. to carry one’s lunch from home, as in a brown paper bag; to eat a lunch brought from home rather than go out to eat. I’m broke, so I’ll have to brown bag it today.
2. tv. to copulate with a very ugly person (woman). (A play on sense 1 The person receiving the action is so ugly as to require a paper bag covering over the face to make the process less odious.) He hated to date and was too proud to brown bag it. So he suffered.
