What is Nerdyknowall?
1.
A proper irritating c***. Someone who thinks they they are clever/funny/charming but are actually very sad people with no friends and usually posesses a small penis. Hence, the need to mask this by being totally obnoxious.
That guy he's talking sh**. He's a real NerdyKnowAll.
Why's he slagging off Burley? He must be a NerdyKnowAll.
