back-yard pup-tent sleep-over 

A back-yard pup-tent sleep-over is when a guy invites a good boy friend over to party and spend the night sucking, fucking, and playing with each other's teen boners until they fall asleep -- then they wake up, take care of each other's morning wood, and then go inside and have eggs and waffles, fruit, and milk that your Mom made.

I had a lot of back-yard pup-tent sleep-overs when I was a younger teenager!
