Fugao' is a slang contraction of the word fugado, which means "fugitive" or "escaped". It's a great example of Caribbean Spanish where the 'd' sound between vowels is often dropped in everyday speech.
In the song, Rauw Alejandro uses it to create a picture of a secret escape with his partner, singing, "Los dos fugao' sin que nadie nos vea" (The two of us as fugitives, without anyone seeing us). It adds a thrilling, "us-against-the-world" feeling to the track.
Okay, so "PONTE NASTY" is exactly what it sounds like: a straight-up, high-energy party song made for the dance floor. Rauw Alejandro, along with reggaeton legends Jowell & Randy, isn't telling a complicated story here. The whole vibe is about letting loose and getting wild with someone you're attracted to. The main command is right in the title: "Ponte sucia, ma' / Ponte nasty" (Get dirty, ma' / Get nasty). The song sets a scene of a secret, intense night out, with lines like "Los dos fugao' sin que nadie nos vea" (The two of us escaped without anyone seeing us).
The lyrics are super direct and all about physical attraction and mutual desire. Rauw describes the woman he's watching, who is completely confident and owning the dance floor: "La pista rompe y ahí es que ella aprieta" (The dance floor breaks and that's where she grinds). It gets pretty explicit, with both sides clearly wanting the same thing. He even throws in a very modern line about her sending him content from her OnlyFans. The song leaves nothing to the imagination, especially with the blunt English line, "I wanna fuck her / She wanna fuck me." Jowell & Randy's verses just turn up the heat, with Jowell getting comically specific, saying things like "Atrévete, dóblate, sóbate y brinquen tetas" (Dare to, bend over, rub yourself and let your boobs bounce). It's a classic, sweaty perreo anthem.
