Why does temperature rise with pressure?

Seems like the pressure would be holding the atoms stiller

Random motion of molecules, in gaseous bodies, is an assumption used to derive physical laws for ideal gas. Hence, it is not to be considered literally as displacements of molecules in gas (or vibrations in liquid ans solid materials), as is done by many.
External pressure on a macro body brings its molecules/atoms nearer to press into each other. With increasing external pressure, primary 3D matter-particles in them lose part of their matter-contents, which form radiations as heat, light or other types of radiations. Temperature is the measure of matter-content level of a macro body with respect to matter-content level of a reference macro body under reference conditions. Reduction in matter-content level is measured as increase in temperature.
