The phrase comes from everyday Tagalog slang, where walang dating means having no charm, presence or impact, and men is a casual filler used among friends online. The clip spread as a short reaction sound on soundboards and in edited videos because its length makes it easy to drop over almost any disappointing moment without setup. It stays popular because the judgement is understood even by viewers who do not speak Tagalog, thanks to the flat tone, and because creators can reuse it for fails, reveals and awkward pauses alike.
