Top Definition
Liquid waste in the bottom of row boats excreted by Sea Lions or other marine mammals. Swaste has the appearance of brown watered down soup and usually has a very pungent aroma.
From the wharf at Monterey Bay California, one can view Sea Lions basking in the sun on small rowboats and dingy's. The bottoms of the boats are commonly filled with swaste.
