Soooo allow me to share my revolutionary chin-related discoveries of yesterday evening! For I learned many things:
a) Butt chins are actually called cleft chins, or dimpled chins. People will assume you have self-esteem issues if you are unaware of this, though they will know exactly what you mean.
b) Said chin clefts are caused by your jawbone not fusing together properly and are technically a birth defect.
c) Superman has one!
d) In Persian literature, cleft chins are considered super attractive and called chin pits or wells… because your desperate lovers and admirers, of which there will be MANY, will be trapped there. Forever. Gently decomposing I guess unless you feed them and stuff?
e) When Persian, cleft-chinned literary characters get into relationships with each other, they create GREAT GIANT EARTH SHATTERING CHIN PIT WELLS! Contemporary science rationalises these away as tectonic plate movement and similar nonsense. We know the truth though: both stranger than, and caused by, literary fiction.
