Güey is a very common and versatile slang term in Mexican Spanish. While it can mean 'dude' or 'mate' in a friendly context, it can also mean 'idiot' or 'fool' when used to describe someone who is easily tricked or taken advantage of.
In this song, the singer says, "Dejen le hablo a un compa que es experto en que lo hagan güey" (Let me talk to a friend who's an expert in being made a fool of). Here, it clearly refers to being tricked or played, adding a humorous and relatable touch to the lyrics about relationship woes.
Eden Muñoz is here to tell us that sometimes, getting rid of someone is actually a win! In "NTP," which probably stands for "No Te Preocupes" (Don't Worry), he's brushing off a past relationship with a whole lot of swagger. He's ignoring "Diez llamadas perdidas al celular" [Ten missed calls to the cell phone] and letting his ex beg, all so she learns to respect him and not betray a good love. He's definitely not in a sentimental mood; instead, he's ready for a big party, "Al estilo Culiacán" [Culiacán style].
He's feeling good about the breakup, singing "Perdiendo gané, ya me quité un peso de encima" [By losing, I won, I already got a weight off my shoulders]. That woman was "muy crazy," and he's already thinking "la que sigue, next" [the next one, next]. He plans to get over her with "mucho tequila" [lots of tequila] and assures us, "NTP, voy a estar bien" [Don't worry, I'm going to be fine]. He's been through worse and warns that if he falls for her tricks again, she'll see a different side of him: "De tonto vuelvo a caer Y de cabrón me va a conocer" [If I fall for it again like a fool, she's going to know me as a jerk]. His ex claims she'll be faithful now, but he's not buying it: "No lo sé, Rick, parece fake" [I don't know, Rick, it looks fake]. He's even thinking of calling a friend who's an expert in getting played to ask for advice – should he forgive her or just move on? It's a fun, defiant anthem about moving on and reclaiming your power after a breakup!
