Belly whoppers is a term used to describe someone falling or diving forward onto their stomach, often causing a loud, smacking sound. However, there are several synonyms for this phrase, including face plant, splat, flop, and crash-landing. These terms all embody the same notion of falling or diving forward onto one's stomach in a comical or embarrassing manner. Other phrases that could be used to describe belly whoppers include nose dive, wipeout, and pancake. No matter the term used, watching someone experience a belly whopper can be both hilarious and cringe-worthy.
