it's only recently I learned that the 'mog' part of 'mogging' stands for 'male of group' (shortened from 'alpha male of group'). so the definition of 'mogging' as like, being deemed superior to someone else in some way or another is using manhood as synonymous with relational superiority.
this was obvious subtext anyway (the whole ideology in which the term emerges is a male supremacist one) but learning it's so explicit and unambiguous was kind of surprising. doubly so since this term is already starting the process of integrating into general usage outside this subculture, first as "ironic," then as decontextualized ("it's just outshining someone!"), and eventually probably as sincere.
casual reminder that it is probably best to not adopt the misogynistic concept of conveying hierarchical superiority in interpersonal contexts as "funny internet slang."
