A doggiest is a person who indulges in and believes in the philosophy that dogs are of a higher level than ordinary humans, and also agrees with the idea that if the hypothetical situation of a heaven and hell be true, then dogs deserve to go to heaven, while all humans go to hell. Alternatively, a doggiest is a person who takes part in the act of sexual intercourse in the much-acclaimed doggy style pose, i.e, someone who likes it in the ass.
