A "kissing cousin" is any cousin that is not a first cousin. In most places in the world, first cousins may not have sex and have babies. But, in most cultures second cousins, and higher can have sex and babies. Degree of cousinship is determined by how many generations the shared ancestor is removed from the individual closest to the generation of the shared ancestor.
