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 willhave 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.
A German word referring to a student's assignment to prepare a report and give a lecture. Often used in English among exchange students in lack of a better word.
How did your referat go?
I didn't get to give my referat, because we didn't have time for me to give it. The professor just totally forgot about my referat, so I'll have to do it next week. And I stayed up all night working on my referat!
