It seems like it's about those who tell their opinions, but don't stand by them because most people don't agree with them.They tell the stories to others who earnestly believe them ("Licking her chops/She looks at the lunatics/She needs another fix"). After saying 'crazy' opinions, they deny believing those things themselves and act like people who believe what they secretly still do are crazy. This is done in order to not offend others or to not appear insane themselves ("I'm only joking/I don't believe a thing I've said/What are you smoking?/I'm just f--king with your head/Only a crazy little thing i read)". There's an echoing question of "Why do I do what I do?" in the background of the song. I think it's a person who does this asking why they cover up what they truly think.
