"bear" vs "chub"

It used to be that "bear" was a man that was larger and hairier. A bear might not be a standard sized man, but he was generally solid, sometimes even muscular, and/or had a "dad bod" sort of look. A bear was always hairy - from somewhat hairy to covered in fur hairy.

A "chub" would be a fat guy, period.

But those definitions have blurred. Extreme fatties spilled over (pun intended) into the "bear" scene.

PS While the furry muscle bear look is appealing aesthetically, those guys are mostly the same skinny twink bitches they were in their 20s, but with 30 more pounds and a chest they no longer shave.

could you please use the preferred terms BearX or ChubX?

I don't believe the Committee has promulgated BMI or body measurement standards yet, OP. Why don't you propose some guidelines to them, say, in a Reddit trolling post or something?

If your waist circumference is...

...greater than 50% of your height, you are probably in or entering "bear" territory (assuming body hair).

...greater than 75% of your height, you are almost certainly in "chub" territory (in which hairiness is irrelevant).

I also associate chubhood with a noticeable lack of mobility, dexterity, and fitness--whereas "mere" bears have no problem with physical activity or reaching various areas of the body.

There’s no need for a distinction

Bear lovers are "Cubs."
