What's a "Swim move"?

What do you call when you get the offensive player using the swim move? Do you call it a hold? It's hard telling a coach you have a hold on his player when the defensive player is behind his player.

No matter who commits the foul using swim move (offense or defense), I use the illegal use of hands signal. When a player holds his/her arms parallel to the floor and impedes the movement of his/her opponent, that is holding, not blocking.
