Sextei is a very modern, informal, and playful slang term derived from the word sexta-feira (Friday).
It's a verb conjugation that essentially means "I've Friday-ed" or "I'm in Friday mode." In the context of the song, it perfectly encapsulates the feeling of relief and excitement when the work week is over, and it's time to party and let loose, as the protagonist does by going out to samba and deboche (mock) her ex.
#Sextei is Marvvila’s feel-good anthem for the woman who survives the grind from Monday to Thursday—crowded buses, rising metro fares, and an ex who still slides cheeky comments under her photos. Even with lipstick already on at dawn, she powers through delayed trains and endless bills, holding it together with a smile that hides the daily stress.
When Friday hits, everything flips. The pagode beats call her to the dance floor, cold beer is non-negotiable, and Instagram Stories become a stage where she playfully roasts the ex. Bills can wait; tonight she will samba “until the world ends,” set her own curfew (none), and embrace limitless freedom. #Sextei celebrates the weekly rebirth that Friday brings—self-love, joy, and unstoppable energy bottled in a catchy, dance-ready track.
