Direct machine translations miss the joke entirely. A literal rendering reads: "Not because you smell like poop should you feel like..." But the humor rests on an untranslatable linguistic mechanism baked into Spanish profanity. In vernacular Mexican Spanish, the expression "sentirse la gran mierda" (or colloquially toned down to la gran caca) mirrors the English slang phrase "to feel like you're hot shit", meaning to act arrogant, self-important, or untouchable.
The punchline exploits the word sentir, which means both "to feel" emotionally and "to perceive / smell" physically. By setting up a false equivalency between smelling bad and possessing high status, the audio constructs a savage double insult. You smell terrible, and your inflated ego is a total delusion.
This type of bathroom-humor wordplay has deep roots in Latin American oral culture. It punctures pretension by pulling the target back down to earth in the crudest terms possible. When translated into English meme formats, creators frequently render the subtitles as: "Just because you stink doesn't mean you're the shit." The clarity of that insult explains why the phrase migrated effortlessly across international boundaries.
