Chinu has the answer. Catsup (or ketchup) is a thixotropic fluid: it undergoes shear-thinning under stress that requires some time for the internal structure to re-form ("heal"). Grease is another thixotropic fluid.

This phenomena is termed as "Thixotropy" and is used in ketchup to prevent spilling during transport. Nowadays all gel based creams use the same principle. In nature also it is observed during eathquakes, peaty type of soils turn liquid due to vibartion of earth and as a result the objects on surface simply 'sink' as in quick sand. This quick sand becomes solid again when the rocking stops, and objects get permanently trapped in earth.

my ketchup is always liquid. it just has a high viscosity so it takes a little shaking to get it to flow right

Ketchip is liquid. Maybe its like more viscuous but it's still liquid.

Uh.. it doesn't to my knowledge. Of course I haven't really studied up on the condiment sciences.
