Not everything you hear can be found in dictionaries. You have to rely on the context. Based on the context, person 1 says he's getting married tonight, and objects to his frineds for going deer hunting on such an important occasion. His friend (person 2) tries to relax him by saying "Don't get upset. First we'll get you legally married to Angela and put you in bed with her, and then we'll go deer hunting."

It's merely a joke between two friends.
