Here is Where You Can Get a Gigantic A** Sub in New Jersey I was recently watching a Tik Tok video on a woman who set a Guineas World Record for having the largest mouth gape in the world. Her name is Samantha Ramsdell and her mouth gape is two and a half inches. When it's measured across, her mouth is more than 4 inches. I've always been told I had a big mouth, but this is actually unreal. Ramsdell has been posting videos of her stuffing ungodly amounts of food in her mouth to the point where she has become Tik Tok famous. She has fans from all over the world asking her to shove different foods in her mouth.
