How would you say, "my stomach's growling"! And also what does, "anviwotman" vle di? Thank You!

My stomach is growling - Vant mwen ap bouyi ( indicates a rumbling stomach because of nervousness, indigestion, etc...)

Other great ways to say I'm hungry in Creole.
Ti trip mwen ap vale gwo trip mwen
Trip mwen ap kòde
Lestomak mwen vid
Grangou anpare m 

Concerning your word "anviwotman", I don't think it exists in Creole. Did you mean 'avòtman' or 'anviwònman'?
