What exactly does it mean if you are double-jointed?

It means that the ligaments and tendons that hold your joints together are a little more lax (loose) then usual. Having this ligament laxity can make a person more prone to sprains and strains, but it can also be helpful in range of motion activities after being casted or otherwise immobilized. Very loose ligaments are commonly seen in contortionists and in yogis in particular.

it truly is a real word. although, double-jointed each and anybody isn't actually double jointed. It has extra to do with elasticity of ligaments, tendons, and muscular tissues. If someone had extra joints than typical, then...properly, they could both be too versatile (and can want to likely crumple) or unable to flow in any respect.

It means your bone wont lock into place where its suppose to so it can go out of the socket when you force it

it means that u have two jonts in that spot and the extra is not so atachibal to the other jont that is way u can move it in wiered places

I means you can hyper-extend your joint without pain
