The Rogan is an abbreviation of the "ROyal groGAN". It applies to a grogan
of complete and absolute perfection in all categories of analysis. The rogan is very rare, and if in a lifetime you lay 2 or 3 of these great creations, you have led a successfull existence.
There is much debate as to whether one can lay a perfect (or royal) grogette
but still not create a rogan. My personal belief is that a royal grogette does not immediately imply a rogan.
See also the shogan
for the antonym of the rogan.
After months of practice, Dennis laid a grogan
so perfect in size, beauquet and valeur it could be termed by no other word than the rogan.
