Pateando literally means "kicking". It's the most energetic and fun word in this song!
Shakira sings the colloquial phrase, "Voy pa'l cielo y voy pateando" (I'm going to heaven and I'm kicking), to express an overwhelming sense of joy and excitement. It’s a vivid way of saying you're so happy you're bursting with energy, a phrase you'd learn from music, not a textbook.
In "Me Enamoré", Colombian pop star Shakira tells the playful story of the night she fell head over heels. She is wonderfully candid right from the start, describing how she showed up with messy hair and a striped bra ("Yo con mis sostén a rayas y mi pelo a medio hacer" [Me with my striped bra and my hair half-done]) and immediately spotted someone special. Even though she initially jokes that he looks like a boy ("Pensé éste todavía es un niño" [I thought this one is still a boy]), she spots him standing alone and makes her move ("Lo vi solito y me lancé" [I saw him all alone and I jumped in]).
What makes this track so much fun is its sheer, giddy honesty. Between sipping drinks ("Un mojito, dos mojitos" [One mojito, two mojitos]) and dancing until exhaustion, she falls hard for his neat little beard ("esa barbita") and round mouth ("boca más redondita"). She even gets wildly ahead of herself, cheekily singing that she would have ten kids with him, but suggests starting with a couple just to practice ("Contigo yo tendría diez hijos / Empecemos por un par / Solamente te lo digo / Por si quieres practicar"). It is a joyful, fast-paced celebration of that dizzying moment when a spontaneous night turns into total infatuation.
