1) A person with teeth that havn't fully grown out of their gums yet giving the impression they've been hit in the mouth by a machete cutting off their teeth in a straight horizonal line with surgical precision.

2) A person with too many metal piercings in their face looking as if they where too close to a grenade when it went off piercing their face with shrapnel(that can later be melted down to make a machete), making them seem as if they've got a bigger more annoying grin or smile.
