Bubbling stomach

Your stomach is bubbling
You hear the stomach of someone bubbling
The prey in your belly is blowing bubbles in the liquid you drank
Your pet's stomach is bubbling just a few minutes after it ate a meal.
Your stomach bubbles when you jut out your belly. (mine was doing this last night)
You swallow air and your stomach bubbles.
You put your ear to your partner's belly and hear their stomach bubbling.
You use the stethescope to listen to your stomach bubbling.
You can feel the bubbles in your stomach.
