Like a handshake event but quicker + high fives instead of handshakes. Quote from this blog "What is a Hi Touch?A Hi Touch is one of your best chances to see your idols up close and personal. Basically, the idols stand on one side of the table, hand up, palm out, poised and ready. You are in a line of people. All the fans file past the idols, giving each one a high five, blurting out the most important thing they ever wanted to say to their faves, if you can get your brain to work that fast!Basically, you walk up to the artists and give each one a high five. That’s how it’s supposed to work."
