Pinza literally translates to "tongs" or "clip". However, in Spanish slang, the phrase "irse la pinza" means to lose your mind, to go crazy, or to lose control.
In this song, Rojuu sings, "Se me va la pinza, ni te puedo mirar" (I'm losing my mind, I can't even look at you). This idiomatic expression adds a layer of intense emotion, showing how overwhelmed he is by the person's presence, making it a captivating and memorable word choice.
Rojuu opens "Muy Lind4" with an English producer tag from Fish Narc before switching into Spanish for the song itself.
The song is about running into someone you used to feel close to and being thrown off by it. Seeing her look so good catches him off guard, so much that he doesn't even want to bother her. He admits he's been tired and a little lost for weeks, like something is quietly wrong that he can't quite name.
Underneath the unease is real longing. He's been trying to find the words to say he misses her, and looking into her eyes makes time slow down. He knows he's not seeing her clearly anymore, that the version of her in his head has drifted from who she actually is, but thinking about her is still the one thing that keeps him going. That gap between the real person and the one he's built up in his mind is what he finds hardest to accept.
