Per the GM advice
The “High Road” specified in Good Egg applies to giving into a person’s Influence or ignoring a Provoke action from other players in addition to simply not raising to the bait from opponents or being the better person in a given situation. The actual stakes of the situation should be important however, simply ignoring a baseless taunt is not enough for this move.
This is a move that triggers when people use their Influence on you. You can't simply take the high road without either rolling to reject their influence or using this move.
