It’s called hyperextension and some people, mainly children and women, can hyperextend their elbow up to 10˚. There are two photos of real people linked in the spoiler’ed text below. You probably don’t want to look if Flan’s arm already makes your stomach turn. Here’s a photo showing a slight hyperextension and another one showing a strong hyperextension.
