butt envelope

A special type of package used for transporting goods. The goods are inserted into a butthole and then the cheeks are clinched tightly to secure the goods.

John: Hey UPS won’t deliver my package.

Jane: Have you tried a butt envelope? It’s good for illicit goods too.

Dirty envelope

The dirty envelope is when you're going down on a girl and you use your tongue to go between the anus and vagina...repetitively

We were sixty-nineing, and I decided to give her the dirty envelope.

Seal the Envelope

When hooking up with a really drunk girl and she passes out before you cum, turn her over and blow your load all over her ass crack. When it drys, it will seal her butt cheeks together and she will have to pry them open the next day - hence, sealing the envelope.

Man this girl was so drunk last night, I just had to seal her envelope.
