Beef in your taco

I showed The Nutty Professor II in my Chinese ESL class yesterday. The students took notes during the movie so that they could ask me the meaning of certain slang words/phrases afterwards.

All of students had the following words/phrases on their lists:
titties
chunky butt
put my beef in your taco

I'm not the type to shy away from sexual discussions, but I have to say it was a wee bit awkward trying to explain "put my beef in your taco" to a group of people who have zero knowledge of American sexual references. After a lot of stumbling over words and a few obscene gestures, they finally got it. The women turned red and the men got a serious case of the giggles.

During the remainder of the class, I would occasionally hear one of the guys mutter, "beef in taco." Of course, that would cause the other students to start laughing all over again.

Thank goodness there are four days before the next class.
