What do they call the projections that have slices taken out of them at the oceans?
The projection is the mathematical transformation from the curved surface of the Earth to a mathematical surface. You can have types of projections based on the mathematical surface (conical, cylindrical...), or based on the features they want to rescue from this transformation (conformal, equal-area...), but, sorry, I've never heard of a classification based on these "slices". Moreover, now that I think of it, even those projections we are familiar with have to be cut somewhere.
Another post in this thread had an example of one, called Goode's Homolosine Equal-area Projection.
No, I know what you mean but that looks like some azimuthal projections put together in some conventional way. Maybe the concept you are looking for is a "composite" projection?
