I love the psychological insights.

In Ireland, when we tell someone to "feck off," it's more than just a throwaway insult; it's a cultural nuance wrapped in humour, frustration, and sharp wit. While “feck” is a milder stand-in for the infamous "F-bomb," it still carries the weight of dismissal. What makes it uniquely Irish is the balance between the indirectness of "feck" and the full-throttle directness that follows, such as calling someone a "gobshite."
