second cousins? Cousins-once-removed? Whatever the one is for my cousin's kids
Since it doesn't look like anyone else has answered: Your cousins' kids would be your kids' second cousins; and your first cousins once removed.
The rule is that if the closest common ancestor is N generations away from one person and M generations away from the other, with N >= M, they are (M-1)th cousins (N-M) times removed.
