When a individual goes to high five another person but gets denied, he high fives the air and screams gibberish at the top of his lungs.

Melania Trump Denied Barron trump a high five. So he did a jacksepticeye

Jackcepticeye is a very loud Irish man who can be very energetic and fun.
Even his 'top of the morning' saying can make you smile.
He reacts quickly to scary and exciting things.
Sean is his name he may sometimes destroy your ears of you wear headphones but over all he is awesome!

"Top of the morning ladies it's your boy jackcepticeye and welcome to..."
