Acomplejabas comes from the verb acomplejar, meaning 'to make someone feel insecure' or 'to have complexes'. It's a less common and more nuanced verb than everyday words, making it interesting and memorable.
In the song, 6ix9ine tells his ex-partner, "Que cuando te conocí, te acomplejabas de cómo te ves" (When I met you, you felt insecure about how you looked). This reveals a deeper emotional context, showing how he perceived her vulnerabilities and his role in her life, making it a powerful and enticing word for a learner.
This song is 6ix9ine's side of a very public breakup story. The title "Respuesta" literally means "Answer," and he is definitely answering some accusations here. He starts by flipping the script on his ex, saying she didn't waste her time with him, she just forgot everything he did for her. He claims he put his own life on hold for her, saying, "yo dejé mi carrera pa' darte una carrera a ti" (I left my career to give you a career).
He gets super specific, listing things he bought like a Jeep and an apartment, and contrasts his success with her situation before they met. The most intense parts are about her daughter. He says while his ex calls him a "rata" (rat), her daughter calls him "papá" (dad) because he gave her the love her biological father (who he later names as the artist Anuel AA) didn't. He admits their relationship was a mess, calling it "un amor de locos" (a crazy love), but he clearly feels betrayed and unappreciated. It's a classic hip-hop track where an artist uses a song to tell everyone exactly how they feel, holding nothing back.
