Place it at the end of a failed boast or gross joke, after the setup has finished, so it lands as the payoff rather than the opening. Follow it with a fart with reverb for a bigger reaction, or pair a long brain fart before it to build up the same crude gag.
Bu Ses Hakkında
This short Portuguese meme clip runs for about six seconds and centres on the phrase peido na minha cara, a crude joke about a fart landing right in someone's face. It feels deliberately gross, silly and awkward, the kind of humour that gets a laugh precisely because it crosses a polite line. It works best as a blunt reaction when a conversation turns childish.
