Three ways to end a discussion like a jackass

(1) Ethos- Invoke a concept which the discussant doesn't understand and refuse to elaborate, stating that it would take too much effort to explain. (Hipster fallacy.)

(2) Pathos- Heap on the vitriol or tears until the discussant backs down or retires out of exhaustion. (Pundit fallacy.)

(3) Logos- Deny rationalism. (Dada fallacy -- similar to the Calvin fallacy.)
