Arranca literally means "to start," like starting a car engine, or "to pull out." It's a powerful and energetic verb that sets the tone for the entire song.
In this track, Becky G uses it as a forceful command. When she sings "Ponte las llantas y arranca pa'l carajo," she's using a strong and very common slang phrase that essentially means "Get the hell out of here!" It's the ultimate dismissal of an ex, telling them to hit the road and never come back.
This is the ultimate getting-over-your-ex anthem! Becky G is completely done with a guy who keeps calling her after she found out he was cheating. She's not having it.
She tells him directly, "Ponte las llantas y arranca pa'l carajo" [Get your tires on and get the hell out]. She's found someone new to take her out on the weekends and makes it clear she's moved on, singing "Ya tu falso amor no va a joderme otro verano" [Your fake love isn't going to screw up another summer for me]. Then, Omega comes in with the ex-boyfriend's perspective. He's arrogant, admitting he's unfaithful but still telling her to dump the new guy because she's his woman. It's a fiery back-and-forth between a woman who has found her power and an ex who just can't let go.
