Rascarte comes from the verb rascar, meaning "to scratch." While seemingly simple, its use in this song is quite memorable and a bit humorous.
Cami sings, "Que te pique una araña donde no puedas rascarte" (May a spider bite you where you can't scratch yourself). This line is part of a series of playful curses directed at an ex-lover, making it an engaging and slightly mischievous way to learn a common verb in a unique context.
"EL PEOR" is a defiant breakup anthem where Cami turns hurt into sarcasm. She opens by admitting she never thought she could resent an ex this much, needling him that his own mother now hears her on the radio.
The chorus flips a classic sendoff into a curse: "you're the worst, I wish you the best" is followed by a wishlist of bad luck — a spider bite he can't scratch, a stone he trips on, lightning striking right before his wedding, and never being able to forget her.
The second verse tracks her recovery: she lost a bet to a tarot reader, poured tequila on the wound and it closed, therapy helped, and the "crazy" reputation stuck while the relationship itself got forgotten. She counts the hours she spent crying, then closes the door on it — she's doing great now, whether or not he's watching.
