look up any word, like fleek:
a subrace of inferior "arses" who practice incest for the benificiary gain of cheese.
Buttkinery takes place between twins often of a male persausion or other male relations.
Activities include Butt sniffing, butt licking, brown nosing, frottage, butt munching and butt hugging.
the cheese is just an unexpected side effect.
