1) From the film "The Social Network," meaning one does not sully one's esteemed status by stooping to the level of the hoi polloi.

Example 1:
Tracy: Beef Jerky?
Tina: Not for a Gentleman of Harvard.
Example 2:

Tracy: Should we sue a squirrely little geek who stole our idea and is worth 25 billion?
Tina: Not for a Gentleman of Harvard.
