to go Aquinas 

1.To engage in theological conversation when under the influence of drugs or alcohol.
2. As in scholastic theologian Thomas Aquinas. To start talking about God when nobody has a clue what you are talking about.

We were smoking some spliff and then he went totally fucking Aquinas on us, and starting explaining how God made the telephone, wallpaper, cannabis, etc...
