What makes a Man... a <i>Himbo</i>?
In any case, the tide seems to be turning to recognize "Bimbo" as a non-gendered term (once male, in the original Italian) so Himbos, Himbot, and Himbeaux may be outdated. Still, there are many other varieties of vapid sluts (reverential) deserving of specific terms:
A sexy, vapid person: Bimbo
A sexy, vapid state that is neither heaven and hell: Limbo
A sexy, vapid action hero: Rambo
A sexy, vapid stance: Akimbo
A sexy, vapid hairdresser: Trimbo
A sexy, vapid screenwriter: Trumbo
A sexy, vapid delicious soup: Gumbo
A sexy, vapid goth: Grimbo
A sexy, vapid emo: Glumbo
A sexy, vapid fidget toy: Stimbo
A sexy, vapid samurai: Yojimbo
A sexy, vapid detective: Columbo
A sexy, vapid elf: Celebrimbo
A sexy, vapid hair-wielding hero: Bobobo-bo Bo-bobo
Other varieties of sexy, vapid beings may yet be discovered by sexy, vapid explorers, or "Bimbologists."
