Bélico translates to "warlike" or "bellicose." It's a powerful and less common adjective that describes someone or something associated with war or aggression.
In this song, the artist uses "pues bélico soy" (because I am warlike) to assert a tough, confrontational, and perhaps dangerous persona. It's a key word that defines the character's attitude and the song's gritty theme, making it memorable and intriguing for a learner.
This song is a full-on declaration of a wild and wealthy lifestyle. The singers describe themselves as powerful and ready for anything, with a whole crew to back them up. They boast, "Traigo a mi mando, la caravana, chingo de monos" (I bring my command, the caravan, a ton of guys), and say they're always prepared because "bélico soy" (I'm warlike). The whole attitude is summed up by the title phrase, "Ni modo que no," which is like saying, "Of course!" or "How could I not?" It's a super confident way of saying yes to everything.
That confidence extends to partying and spending money, especially on women. The lyrics get very direct, offering to buy a woman a Rolls Royce, a Birkin bag, and a Rolex. It's all about living a life of excess with yachts in Puerto Vallarta, expensive cars, and no limits. They see a woman they like and immediately say, "Por ese culito, yo le doy dinero" (For that little ass, I'll give her money). It's a blunt look into a world of power, luxury, and getting exactly what you want.
