dick in a box
A present that a man may give to his girl friend. It is ill advised to give this gift unless you are as cool/cooler than Justin Timberlake. That way, if the girl doesn't like it, she can always find solace in the fact that you're cooler than Justin Timberlake, who is pretty cool in his own right.
Example:
Average Joe: Here I got this for you.
Girl: What is that?!? Is that your dick in a box? That is gross.
Average Joe: Why can't I be as cool as JT?!?!?!?!?!
Average Joe: Here I got this for you.
Girl: What is that?!? Is that your dick in a box? That is gross.
Average Joe: Why can't I be as cool as JT?!?!?!?!?!
