Character getting way too stuffed but it's 10% food 90% air
trapped air my beloved,,,,,, (& these can definitely overlap so it might be fun to combine these various Plot Aspects into full scenarios)
š Your character's belly is bulging like crazy after eating a portion of their meal, tight and round and undeniably out of room. They and the people they're with think they're definitely too full to eat any more, but your character lets out an absolutely ridiculous burp that startles even them, and suddenly they have plenty of space to keep eating.
š½ļø Your character knows they're perfectly capable of cleaning their plate. They also have a tendency to swallow a lot of air while eating and they often let out little burps during meals to let it out, maybe not even realizing that they're doing it. When they're eating with someone they don't want to burp in front of, though, they find themself getting full a lot faster than they're used to. They don't want to look silly for taking/ordering the portion that they did so they keep going, determined to finish their food even though their belly is struggling to squeeze in anything else on top of all that air.
š£ļø Your character never shuts up. They can talk anybody's ear off without even realizing they're doing it, and their friends fondly roll their eyes and deal with it. Of course, talking while eating results in a lot of swallowed air. One day, they're out for lunch with friends, and after chattering away with their mouth full the entire time, they're left with an uncomfortably bloated tummy, tight and sore and far too full. Suddenly they're not so chatty anymore now that they're not feeling too good.
𤵠Your character is eating at some kind of date/event that they want to make a good impression at, and they avoid burping the entire time they're there. Of course, this means that once their belly fills up with any air they've swallowed with their food, they run out of space, and though they feel pretty stuffed by the end of it, they haven't eaten much. Once they're finally home and they can let all that air out, they find that they're still very hungry--even more so than usual since their stomach is now all stretched out.
š Your character has to go out today, and they're struggling to fit into their outfit after eating, their belly seemingly far too stuffed even though they didn't eat all that much. After some straining and squeezing, they're just about ready to put on something looser when their stomach, having been jostled around plenty, finally lets all the trapped air out in the form of a huge burp, deflating their round belly and allowing them to get dressed in their outfit of choice.
ā±ļø Your character is in a rush to get to some kind of meeting/appointment/event, and they have to eat fast to make it in time. They succeed both in wolfing down their lunch and being punctual, but they arrive with a bloated, rumbly, uncomfortable belly, and now they're looking for an opportunity to let all that trapped air out discreetly before anybody notices.
š Your character feels absolutely stuffed even though they haven't eaten much, and the people they're with are teasing them for having such a tiny capacity. As it turns out, their belly was mostly full of air, and once a big burp frees up some space, they wind up out-eating everybody else at the table.
