COUSINCEST = COUSIN + INCEST, ie, when cousins have sex.
"Cousincest" is a misnomer. Cousin sex is NOT incest according to Modern Medical Science (cousins have a 96% chance of producing a normal, healthy child), the Bible, or most marital laws around the world (including Europe, Canada, and much of the USA).
