Dogmatic Opinion
It is not onomatopoeia.
Currently, all female celebrities named “Depparin” when searching for images of “Deppari” on Yahoo!
Depparin’s nickname comes from “Deppa（bucktooth）,” but Deppa（bucktooth） has little association with “Deppari”.
It is difficult to imagine a specific shape by “Deppari.”
An angular projection rather than a round bulge image.
It may be functionally necessary, but there are nuances that get in the way.
It is also a convexity(凸）corresponding to a dent (concavity 凹).
Proximate Expression
bulge
protruberance
tumor
