look up any word, like darude - sandstorm:
In Welsh Deryn means Bird! In Urban English Deryn means smart, beautiful, sexy and funny. Deryn can sometimes be an airhead but always makes up for that with comedy and humour! Deryn's also have their own language called 'Derynism's' She is a godess in the bedroom and will be the best lover you have ever had! There aren't many Deryn's around so if you find one please do NOT let her go!
Man1: Whoa look at that bird over there, she's hot!!

Man2: No that's Deryn!
