San Diego Flatbed 

Rather than booking a hotel room, just arrive and leave your bags some place safe like a car or a friends room if applicable. Proceed to party in the hotel and meet a hot chick who already has a room. When you get free room with her and free service from her, you have scored a San Diego Flatbed.

I never paid for a hotel room because I pulled a San Diego Flatbed.
