stone-cold
Completely without warmth
Stone-cold means completely cold, with no warmth remaining: The coffee sat stone-cold on the desk.
Extended to mean absolute or total: stone-cold sober, a stone-cold killer.
The intensifier works because stone suggests something hard, lifeless, and incapable of warmth.
In sports, a player who is stone-cold has gone quiet—no recent baskets, no momentum.
