Belly ocean
When someone's stomach is so fat they can move their belly in a way that it resembled the waves of an ocean.
When she started twerking, her belly ocean started rolling in waves.
Ocean Belly
The feeling you get after drinking too much liquid and you can hear the sloshing in your belly. The sound you used to try and hear when you were little and had too much luquid to drink.
Ugh, I drank that whole 44oz drink I have some bad Ocean belly.
