Not in all the cases man. Sometimes, you see that for weak corners, you have better stability
 

SS, TT, FF corner

I think you should meet the spec in all coner condition

This is true. The only hard-to-define thing is what's the worst corner, because it's entirely dependent on the specific circuit/specification(e.g. FF is the best for speed but the worst for current consumption for an application). It's very vague to describe a worst case

Added after 1 minutes:

I've seen in the past cases when FS or SF (for NMOS and PMOS) are the worst corners
 

SS, TT, FF corner

Worst case usually depends only on what you are doing, sometimes worst case is FF , and sometimes with SS or SF or FS .It depends of the circuit... unfortunetly there is no rules for that.
