when people feel comfortable with food and eating and expressing how comfortably full they are
Not apologising after a burp/ hiccup but instead saying "oops" innocently and knowing exactly how the other person feels about that
Saying "Ugh look how full I am", taking your hand and pressing it against the tummy
Teasing you with sentences like: "Poor me, I overdid it. I think I need a belly rub" "I'm so full, you should feel it", "That was so good I just couldn't help myself" "I'm gonna have to open my belt after this, maybe you could help me.."
Talking about what they ate and how much just to see your reaction
Patting their tummy so loud that you can't overhear it and looking at you with a provocative grin on their face
Talking about how nice their tummy looks and how much they know that you like it
Slightly pressing their tummy against you at every chance they get to remind you of the grip they have you in
Chugging a large glass of water/ water bottle and keeping eye contact throughout the entire time
