I didn't realize I was a fan of laconism: 
A laconic phrase or laconism is a concise or terse statement, especially a blunt and elliptical reply.

It is named after Laconia, the region of Greece including the city of Sparta, whose inhabitants had a reputation for verbal austerity and were famous for their blunt and often pithy remarks.
NFL coach Bill Belichick's take on a recent rule change is along the same lines:  "Whatever the rule is, it is."  But that might instead be a tautology, or a truism, or a platitude.  They're all sort of related. #language
