Apantallar means "to show off" or "to impress," a lively, colloquial verb that captures someone trying to make a big, often exaggerated impression on others.
In "Me va querer apantallar con su pistola" ("He's going to want to shield me with his gun"), Gloria Trevi uses the word to describe a man trying to impress her with bravado and danger instead of real substance.
Get ready to feel empowered with Gloria Trevi's "20 Segundos"! This song is a sassy anthem where Gloria takes on a boastful 'bad boy' who thinks he's all that. She's not impressed by his attempts to show off, whether he's talking about his "bate y sus pelotas" [bat and balls] or trying to "apantallar con su pistola" [impress with his pistol] – which she quickly dismisses as just his cell phone!
Gloria makes it clear that this guy, who approaches her "como un rey" [like a king], doesn't stand a chance. She tells him, "Tú no me duras a mí ni 20 segundos" [You won't last 20 seconds with me], playfully challenging his bravado. She even pokes fun at his dancing, saying "Tú no bailas Gangnam Style" [You don't dance Gangnam Style] and "Tú no mueves las caderas ni pa caminar" [You don't move your hips even to walk]. It's a fun, confident song about a woman who knows her worth and isn't afraid to put a conceited man in his place!
