MF, from what I understand, even cuffed pants can have a back end that is longer than the front-end. However, I am pretty sure that it's really much more of a reality it when the pants are originally made that way.
Even I have to keep people guessing from time to time.
However, I will add, I know that there are phrases that I like that probably make other people want to barf. I think that's just the way of silly phrases. To me they mostly all fall in the live and let live category.
