Perrengue is a very Brazilian Portuguese slang term that describes a difficult, uncomfortable, or embarrassing situation, often one involving financial or emotional struggle. It's a word that perfectly captures the feeling of being in a bind or having a tough time.
In this song, the singer uses it to describe the emotional suffering his heart went through after a breakup, implying that his ex-partner will experience a similar
Perrengue is a breakup song about being the one who kept trying.
The singer says it was not just once that he went looking for a way back. He kept pressing the same point, wanting peace while she wanted a fight, and his name sat in her phone under "answer later." So he ended it. He admits he felt awful and that he is sad, but he also knows the simple rule of it: when one person does not want it, there is no couple left.
The rest of the song is what he expects to happen next. He will miss her, and he will drink while he remembers. But she is going to go through the same rough patch, the same perrengue, that his heart already went through, and it will hit her the day she realises she lost him. Everything that leaves comes back, he says, except him.
Underneath the hurt there is a lot of swagger. The band drops into a bachata groove halfway through, the crowd lifts their hands, and a sad story turns into something you can dance to.
