 Recent social acceptance and popularity has resulted in the emergence of highly adorned dildos, which are often made of expensive materials and may be jewelled.The etymology of the word "dildo" was long considered unclear, but the third edition of the "Oxford English Dictionary" concluded in 2018 that the word originates in nonsense syllables common in early-modern popular ballads (not dissimilar to the still-familiar nursery rhyme phrase "hey diddle diddle"), which came to be used as a coy euphemism for dildos.The phrase "Dil Doul", referring to a man's penis, appears in the seventeenth-century folk ballad "The Maids Complaint for want of a Dil Doul".
