Thickened

Epoxy is often thickened with fillers to prevent it from sagging or oozing out of a joint before it's cured. Thickened epoxy is also used to create fillets and endpours. In some applications (like endpours), epoxy can be thickened just to decrease weight in general. Thickened epoxy is often referred to by corresponding food consistencies (Peanut Butter, Mayonnaise...) Nick calls it "Dookie Schmutz" in his book. Fillers do not reduce the strength of epoxy.
