Pichear is a colloquial term, especially common in some Latin American countries, that means "to ditch" or "to blow off" something or someone. It implies intentionally skipping an activity or ignoring a person.
In the song, the artist sings, "Hoy voy a pichear el PlayStation, eso es de una / Pa' ir a verte con la combi Ecko, las trenzas y el durag." He's saying he's going to ditch playing PlayStation immediately to go see his love interest, highlighting his eagerness and the importance of seeing her over other activities.
Puerto Rican singer Omar Courtz hits you with an unfiltered wave of nostalgia in "POR SI MAÑANA NO ESTOY" (Just in Case I Am Not Here Tomorrow). Switching effortlessly between Spanish and English, he is sitting alone at night, staring at his phone, wishing he could FaceTime an ex. He admits straight up: "Me cuesta admitirte that I miss you" (It's hard for me to admit to you that I miss you). He takes us all the way back to high school romances in 2016, skipping PlayStation sessions, sneaking around her parents' house, and wearing an Ecko streetwear outfit with braids and a durag. He even drops local cultural nods, like playing a huge concert at Puerto Rico's famous arena ("Hice un choli pa' cantarte" / I booked a Choliseo show to sing for you) only to find her seat empty.
What makes this track stand out is the clash between his newfound success and the old memories that still haunt him. He jokes that he is about to win a Grammy just by writing songs about her, yet he still has to lie in interviews about who his original muse is. Instead of being bitter that she said he would never make it in music, he leaves this song behind as a parting gift in case he is gone tomorrow: "El tiempo cura todo, sana cicatrices" (Time heals everything, it heals scars). It is a late-night confession packed with real, local memories of prom night, car rides in his dad's car, and walking the stairs of the historic seaside neighborhood La Perla in San Juan.
