Etymology

Origin of foment

First recorded in 1350–1400; Middle English fomenten, from Late Latin fōmentāre, verbal derivative of Latin fōmentum “soothing application, poultice,” contraction of unattested fōvimentum, equivalent to fōv(ēre) “to keep warm” + -i- -i- + -mentum -ment

Explanation

Stand outside the school cafeteria passing out flyers with nutritional details on school food, and you may foment a revolution — foment means stirring up something undesirable, such as trouble. You would never say, "Hooray, we fomented a revolution." Instead you'd say, "Those good for nothing scalawags fomented the rebellion." Don't confuse foment and ferment. Ferment can mean "to stir up" in a good way — a football game can ferment excitement in a town, or foment trouble through traffic tie-ups and litter.
