Hatchet, by Gary Paulsen
(Edited)

to roll about lazily, especially of an animal in mud or shallow water; or the muddy hollow or puddle where it does so

to excessively give into a desire (indulge)

This is often said of something negative such as self-pity when no attempt is made to move beyond it. But it can also be used without negative connotation to indicate that someone is enjoying a lot of something such as luxury or rest.

to move with difficulty; or perhaps just to move through water or in a rolling/wave-like manner
