My daughter used to call unicorns "horny horny" when she was about 3yrs old up until she was 5, it was so funny hearing her say "ma want ma horny horny", at first we didnt know what she was on about, but then she went and my mums pony off her bed "oooh lol that horny horny"
I have called unicorns horny hornies ever since and VERY nearly titled this "'who wants to be a horny horny'... that could have been embarressing
