Jiggly with a purpose

When a girl is almost considered thick but they’re not quite there. This in no way means that they’re fat, it just means that their jiggle isn’t quite as concentrated as it would be on someone who could be considered thick. They have some jiggle... not enough to be considered thick, but enough to serve a purpose.

Guy 1: Dude that girl is thick af

Guy 2: Nah idk about that bro. I mean I she’s got a little junk in the trunk but she’s not quite thick you know?

Guy 1: What is she then?

Guy 2: She’s jiggly with a purpose
