"Beastlyalty" is a playful portmanteau of "beastly" and "loyalty," often referring to a fierce or intense loyalty to a particular group, cause, or individual. It can imply a loyalty that is almost primal or instinctive, akin to the loyalty found in the animal kingdom. This term may be used in various contexts, including social dynamics, fandoms, or even personal relationships, to emphasize unwavering support.
