"Smite targeting" is a shorthand to mean some effect that can be targeted at any space within a certain radius and usually in line of sight from its originator, but not necessarily in a direct line with them, like a scroll of stinking cloud or the advanced fireball spell. Such effects are often something that comes down on the target space from above like the smite of a god, rather than flying there in a line.
