The game of hiding a used condom in a sexual partner's handbag or purse after intercourse.
The name derives from the slang word for taking a meal from a restaurant home in a bag, but replacing the meal with semen, and the paper or plastic bag, with a condom for the recipient to 'Take home for later'
Dude, I did this chick, she had know idea i was doggybagging her after we finished, gave her a little surprise for later
I couldn't believe it, she went for the Doggybag. There I was just smashing her in from behind and suddenly she decides to start giving my balls a tickle at the same time. It was just something else...
