Calzarme comes from the verb calzar, which means "to put on shoes" or "to fit (shoes)". It's an interesting word because while it literally refers to footwear, it can also carry a more metaphorical meaning of fitting into a role or situation.
In the context of these lyrics, "A calzarme scheuer y empezar" (To put on my shoes scheuer and start) suggests getting ready or preparing to face something, possibly a challenge or a new beginning. The addition of "scheuer" (which might be a proper noun or a slang term not immediately clear from the lyrics alone) makes it even more intriguing, hinting at a specific style or attitude being adopted.
La 25's "Sucia Mujer" is a rock and roll ride from Argentina, and it feels like a late-night conversation with a friend who's had a bit too much to drink. The singer is feeling a mix of defiance and longing, telling someone, "pues loco vamos, me queda una más" [well crazy, let's go, I have one more left]. It's all about a woman who has left him, and he's still reeling from it, wondering where she is and who she's with. He sings, "no sabes dónde el que te hará sentir" [you don't know where the one who will make you feel] – it's a bit of a taunt, a bit of a wish.
He's ready to move on, but also stuck in the past, saying, "me entendés que te dejaron a calzarme scheuer y empezar en dólares" [you understand that they left you to put on my shoes and start in dollars]. It's a blunt way of saying he's been through it all before. The song has this repetitive, almost hypnotic feel, especially with the line "una más para mí la mujer" [one more for me, the woman], which could mean one more drink, or one more chance, or just one more thought about her. It's a raw, honest look at heartbreak and trying to find your way out of it, even if you're just driving around in circles, as he mentions, "en ese auto el negro de regreso ya daremos un paseo que te llevará al centro norte" [in that black car, on the way back, we'll take a ride that will take you to the north center].
