I dig people who subtly use songs/albums/artists in conversation.*
Examples: My friends are electric; I feel like the creek that drank the cradle; Well you can't be a pimp and a prostitute too.
* Note: Breaking out in song in the middle of conversation is a common occurrence when hanging around me. **
** Note: Participation is only mandatory if you've seen Cooper, or if you are the one making the reference in the first place.
