How to unlock the Smart Mouth achievement in Bully - Definitive Guide
It is best to do this after knocking someone out and they are lying on the floor, that way they can't move and you can repeatedly taunt them providing they don't fade out.
You can do more than one taunt on the same person and it will count.
Taunts are used to scare people and stop them from attacking you. In order to perform a taunt you must first lock onto another character by holding and then pressing . A taunt is symbolized by a thumbs down symbol over the button. Jimmy will then proceed to say hurtful words to the person. Each time you do this it counts as a single taunt. You can spam this on a single person by repeatedly taunting them until the trophy unlocks. Taunts will usually make the person hostile towards you, however, as you complete English classes you will earn greater abilities to perform taunts without getting beaten up.
You can track your progress for this trophy in the Stats menu by pressing and then navigating to Stats > Social > Social Interactions > Taunts.
