What does ASPH mean to you?

I don't mean "Is the Leikor Bloktron 42mm 1.3 ASPH a good lens?", I mean what do you understand about "aspheric" *photographic* lenses? What are they for AFAYK? Are there pros and cons? What level of insight would you need to part with 2x the cash? 4x? Shut-up-and-take-my-money... umm... 'times'?
