Fría literally means "cold" (the feminine form), but in this song and in many Spanish-speaking countries, it's popular slang for "a cold beer". It's a casual and friendly term you'd hear among friends.
Enrique Iglesias uses this in the chorus, "Sólo salí por una fría" (I only went out for a cold one), as a playful excuse to his partner for being out late. Learning this word is a fun peek into everyday Spanish slang and the central theme of this catchy song.
Spanish pop star Enrique Iglesias teams up with Cuban artist Yotuel to tell the age-old story of coming home way too late with the flimsiest excuses imaginable. The narrator swears he only stepped out for one beer—that is what una fría literally means, "a cold one"—pleading, "Baby, confía / Sólo salí por una fría" ("Baby, trust me / I only went out for a cold one"). He admits he stayed out partying and never made it back on time, but insists he is totally innocent. The best part is watching him scramble to explain the physical evidence against him: why does his shirt smell like perfume? Because someone hugged him after a soccer goal ("Metieron un gol / Y me rompieron la camisa... Nos abrazamos y por eso es el olor"). Why is there a red stain? A stranger tripped and spilled wine on him ("La mancha de vino es porque ella tropezó"). It is hilarious, shameless, and completely chaotic.
Throughout the track, both singers try to brush off the drama as gossiping friends and terrible timing. Whenever his partner called, the bar was erupting in noise ("la bulla") right as his favorite tune dropped. Yotuel jokes about nearly falling into temptation when someone pulled him onto the dance floor, yet the excuse always circles back to absolute fidelity. He even claims that when someone kissed him out of nowhere, his thoughts were only with his girl back home. He knows he looks like a descarado (a cheeky, shameless guy with no manners), but he swears on his life that going out for a single cold drink just got hopelessly out of hand.
