Reverse thumb pulling

[liono]

Since I’m still in my teens what if I did reverse thumbpulling on my bottom jaw the mandible to make my jawline more defined
Also what if I put my thumbs under my neck where the jaw is and pushed outward especially at the base of ramus
I just want a good jawline how do I actually do it help please
