Alpha

The Alpha is considered strong, dominant, confident, charming, charismatic and other traditionally masculine traits. Often used by the kink community in Primal play and play fighting.

Originating in pseudoscientific terms for men derived from the designation for alpha and beta animals in ethology. Classically it has been used as a way to indicate "the most dominant" person in a particular group.

Criticism

The idea of "Alpha" is derived from a masculine cultural background which some people may consider problematic. There has been documentation that disproves the myth of the Alpha Male (second source). The term is also sometimes associated with manosphere groups, in particular incel groups.
