One who knows a little about something and freely boasts his/her knowledge purely for the sake of sounding more educated than others. A blend of the words "Obnoxious" and "Aficionado"
Chris always gathers information before a trip so he can boast about his knowledge to everyone in conversations as though he is educated on the subject. He is such an obnoxionado, it really makes my eye twitch.
