In Vanilla Sky, Thomas Tipp tells David that the board (a.k.a, the seven dwarfs) has a nickname for David -- "Citizen Dildo".
I've seen this film many times and the only curiosity I'm always left with is the meaning behind this nickname. The only thing I can think of is maybe it's related to how David doesn't take his work seriously, and/or all he does is try to please everyone [and therefore is being used by others for pleasure/entertainment].
Is there a concrete meaning behind this nickname? Is it maybe a play-off of some other phrase / common nickname?
