1 the 'dropped' stomach feeling that you get when riding a roller coaster; 2 having an upset stomach where your food is passing from your stomach to your bum very quickly.
3. being so full after a meal, there is absolutely no more room left for another bite, every part of you is totally and completely full.
1. Whoo! That ride totally made me feel tum to bum.
2. After eating that old kfc and cole slaw we all were tums to bums.
3. Wow, that buffet was great! But now I'm just tum to bum.
