The word "gross"...
Has no place on MFP to describe any person.
Please stop using it, even if you find someone too thin, too fat, too muscular, too flabby, unattractive, etc. It's hurtful, rude, and unnecessary. In fact, it's best to avoid using words like "gross" and "disgusting" to describe ANYONE. People open themselves up on this site by posting their real pictures all the time. It's rare that we look like models or hunks. There are all different body types here: thin, tall, short, heavyset, curvy, obese, muscular, etc. Inevitably, you'll see people you don't find attractive, perhaps several such people. It's part of being on a fitness/weight management website. When that happens, please try to avoid using nasty language like this to describe them. They are human beings just like you and deserve to be treated with respect regardless of their body shape or size.
Please think about what you type and if you would like to be called those things before you post about someone else.
