High Five
"So… what do we do?"
"We just raise our hands, and hit them together."

"And… how is what we did cold?"
"No, cool. It's an Earth term that means awesome or neat."
"And I guess that us escaping from Borusa in the manner that we did is… 'cool'?"
"Well… yeah."
"Oh. Cool," Koschei said, before giving Theta a high five.
