Synonymous to having a thick skull. Thick skull means there's less space for a brain, implying you have a small brain and therefore you have limited mental capacity. Thus, a thicker skull means a denser one because extra thickness adds extra mass to the current volume of your head.

Density = mass/volume. When the mass of your head increases from being extra thick, the density is increased as a result.
Person A: 1+1 = 3
Person B: You dense motherfucker!
