@Tay Tay Its called Califlower ear its common in people that do any sort of fighting its just a defomity in a persons ear that happends when the cartilage in a persons ear is damaged and blood or fluid build up under the skin causeing the bubble type look . So in Jakeyungs case becuase of the fighting he does he gets hit in the ear a lot causeing fluid to build up under the cartilage of his ear which is Califlower ear. It can be permanent if it doesn't get treated fast.
