Lecherous or sexually aroused, the word has been around since the mid-17th century. Its origin remains obscure but there are two suggested origins. The first is that it possibly derives from rand, a word that dates from the late 16th/early 17th century but is now obsolete, meaning to rant and rave in a wild wanton manner. The second is that it derives from the Hindi randi-baz meaning lecher and was brought back to England from India by the British military. On balance, there appears to be more support for the former origin than the latter.
