Clontarf

A high-ranking Dutch wizard.

I haven't seen anyone as powerful as Dumbledore since the days of Clontarf.

The Stanton effect

A phenomenon describing a seemingly osmotic transferral of grossly unjustifiable confidence from one individual to another caused by an overdose of social contact with the Stanton effect carrier.

Person 1: “Man, I saw Brett from college last week he’s been working as Trump’s office manager at the White House and MAN he is an arrogant SOB these days”

Person 2: “Classic case of the Stanton effect bro.”
