Interestingly enough, lanugo is the same word/same meaning in Spanish. Lanudo is related and means "wooly". They both come from the latin "lana" meaning wool. Lana in Spanish means wool too, but in slang also means money, especially accompanied by one of these hand gestures: for a small amount of lana, rub the fingertips of the thumb and first two fingers back and forth lightly several times; for larger amounts, hold your thumb and index finger extended in a bracket with the other three fingers folded into the palm. Snap the whole hand forward, stiffly, once only and maintain for a count of three.Now you're doin' that crazy hand jive, hijo
