Enfiestarme comes from the word fiesta (party) and means "to party hard" or "to get the party started." It's a more active and intense way of saying you want to go out and have a good time.
In the context of this song, the singer is clearly in a mood to keep the party going all night. He sings, "Sigo buscando donde enfiestarme" (I keep looking for where to party hard), emphasizing his desire to continue the celebration and not go home.
"Shot" is a straight-up party anthem from Banda Los Recoditos, a Sinaloan banda group known for upbeat, danceable tracks. The whole song is built around one simple idea: going out for the night and losing count of the drinks.
The singer is at the beach, in a club, out with friends, and he's not ready for the fun to stop. Between shots of tequila and beer, he keeps repeating the same line: after a couple of rounds, he can't remember a thing. It's playful rather than serious, more about the rush of a big night out than anything deeper.
The chorus leans on the band's own name, turning "Los Recoditos" into part of the chant itself, which is typical of banda music - the group becomes part of the party. It's a fun, high-energy song made for dancing, not for reading between the lines.
