The act of inserting the name of any obscure cultural institution into a conversation in an effort to accelerate the building of rapport with someone, or to make one's self appear to be more important. Typically considered by intelligent people to be a negative habit.
Here is an example of name dropping in context.
"I totally saw this guy I used to work with at the Bright Eyes show last tuesday!"
With the intended response being:
"woah, you listen to Bright Eyes!?"
One more example
"I was getting off the train and my Don Delillo book fell right out of my bag and onto the tracks!!!"
