    n 1: an honorary law degree [syn: Doctor of Laws, LLD]

The Devil's Dictionary (1881-1906):

LL.D.  Letters indicating the degree _Legumptionorum Doctor_, one
learned in laws, gifted with legal gumption.  Some suspicion is cast
upon this derivation by the fact that the title was formerly _LL.d._,
and conferred only upon gentlemen distinguished for their wealth.  At
the date of this writing Columbia University is considering the
expediency of making another degree for clergymen, in place of the old
D.D. -- _Damnator Diaboli_.  The new honor will be known as _Sanctorum
Custus_, and written _$$c_.  The name of the Rev. John Satan has been
suggested as a suitable recipient by a lover of consistency, who
points out that Professor Harry Thurston Peck has long enjoyed the
advantage of a degree.
