Cabrón is a versatile and very common slang word in many Spanish-speaking countries, especially in Cuba where Gente de Zona is from. While it can be an insult (meaning 'asshole' or 'bastard'), it's often used informally among friends to mean 'awesome' or 'badass', or even as an intensifier.
In this song, the line "Contigo yo la paso cabrón" means "With you, I have an awesome time" or "With you, I have a blast." It's a strong expression of enjoyment and excitement, showing how much fun the singer has with the person they're with.
The whole song is one demand, repeated until it sticks: Mami, yo quiero tenerte pa' mí solito [Baby, I want to have you all to myself]. No sharing, no negotiating. Gente de Zona build the case out of appetite rather than romance, and they are blunt about it: Yo no soy Adán pero quiero morder la manzana [I'm not Adam but I want to bite the apple], then Tú estás pa' comerte de lunes a viernes [You're good enough to eat from Monday to Friday], with the weekend set aside for more of the same.
What keeps it light is how pleased with himself he sounds. Contigo todo está bien, no me hace falta nada [With you everything is fine, I don't need anything] is a man who has checked and found nothing missing, and he thanks God for it twice. Then the flirting stops and the dancefloor instructions start: Y bájate, súbete, dale [And get down, get up, go for it]. He does admit the risk. Porque eso está rico, pero es peligroso [Because that feels so good, but it's dangerous] is the closest the song comes to second thoughts, and it lasts one line. The Cuba to Miami shout-out at the end tells you where the beat came from.
