The term 'bulge outwards' can be described as distending, which is a seven-letter word. Distending means to swell or expand outward, usually due to pressure from within. This term is often used to describe the shape of something that has been filled with air or liquid, such as a balloon or a water-filled container. It can also be used to describe the shape of a body part that has become swollen due to an injury or illness.
