This one is pure party fuel. Pitbull spends the whole track hyping up a girl on the dance floor, and almost every line is either an order to dance or a compliment. The word you will hear most is "dale", a Caribbean and Latin American favourite that means something like "go on!" or "do it!". Stack it with "mamacita" (hot mama, a flirty way to address a woman) and you have the hook: "Dale mamacita boom boom" (Go on, mama, boom boom).
The verses are cheeky and a bit much, which is the point. He tells her "no te hagas la monja" (don't play the nun), meaning stop pretending to be innocent, and asks "¿Dónde lo quieres? ¿En la cama o en el sofá?" (Where do you want it? In bed or on the couch?). Listen for two handy expressions: "ay qué nota" (oh, what a buzz), slang for feeling great or tipsy, and "por si las moscas" (literally "in case of the flies"), an idiom that just means "just in case". His drink order, "limoncito, agua y vodka" (a little lemon, water and vodka), tells you how the night is going.
The chorus switches to "Muévelo" (move it), with lines like "ella quiere ir de fiesta" (she wants to go party) and "ella quiere locura" (she wants craziness), so it is a great song for practising the third-person "ella quiere" (she wants).
