One who does nothing adventuresome or active over their weekends.

Usually a weekend wimp is not spontaneous and does nothing of value or purpose over their weekends. Ironically though, their weekends are probably more spirited and interesting than their week days - how sad. Many weekend wimps spend hours and hours of watching YouTube videos in their bed, constantly picking up food from ToGo eateries and pickup only restaurants. If there is a Briscos within reasonable distance, 98% of all meals will be purchased from that location. Weekend wimp's tend to over-enjoy the fork dispensers and milk selection at these types of places.
