Maleantean comes from the word maleante, meaning 'thug' or 'gangster'. It's a slang term that describes acting tough or rebellious, often in a playful or performative way.
In the song, the lyric "En la disco todas maleantean" suggests that even the 'finest' or most refined women let loose and adopt a more edgy, street-smart persona when they're out dancing. It highlights a contrast between their usual demeanor and their behavior in a party setting, making it an intriguing and culturally relevant word.
The title is the hook's initials. "¿A quién no le gusta el perreo?" (Who doesn't like to dance reggaeton?) comes round four times, and A-Q-N-G-P is what survives if you keep only the first letter of each word. Netón Vega made his name on Mexican corridos; here he spends the whole song in a club instead, trading verses with the Colombian reggaetonero Ryan Castro and saying so outright — "México, Colombia, pa' que bailen reggaetón" (Mexico, Colombia, so they can dance reggaeton).
Between the choruses is one night, told without varnish. Someone walks in — "La gata desde que entró, se sintió" (The girl, from the moment she walked in, was feeling herself) — and the narrator drops any pretence about where the evening goes: "Mami, tú no eres una santa, tampoco soy yo" (Baby, you're no saint, neither am I). Most of the boasting is about the room rather than the man: a van parked outside, an after-party with an entry rule, a European car. The sharpest line admits the whole thing is a performance on both sides — "Hazte la que no quiere, yo voy a hacer que te creo" (Pretend you don't want it, I'll pretend to believe you).
