"Robin, what's an eskimo kiss?"

The boy wonder muted the TV and turned to Raven, who was reading a book beside him on the couch. He tilted his head and frowned. "Why do you want to know?" He asked. It was kind of an out of the blue question, especially for someone like Raven.

"Read here." Raven held up her book and pointed to a specific part of one of the paragraphs. He read through it, in which two of the characters gave each other an eskimo kiss before leaving. He pulled back, and Raven was still wearing that puzzled expression.

"An eskimo kiss is like this." Robin leaned forward and gently touched his nose to Raven's own, pulling back after a second.

She blinked twice, then looked down at her book. "I don't get it." She said after a moment.

"What do you mean?" Robin asked. He'd just given her the type of kiss she was confused about, so what else didn't she understand?

"I mean, if they were that close, why wouldn't they just kiss normally?" She clarified.

"Because people who were exploring cold regions had protective winter gear covering their faces, so they couldn't kiss someone on the lips." Robin explained. "Instead, they would touch their noses to each other in place of a normal kiss. That's why it's called an eskimo kiss; only your nose and your eyes were exposed, if that." Robin told her.

"Oh." Raven replied. "Azarath was a very warm place." She said simply.

Robin immediately understood. Hard to imagine what an eskimo kiss was if your home dimension didn't have any eskimo's in the first place. He turned to look at her, but Raven had pulled the book up so it was blocking her view of Robin.

Good thing, too. He might not have ever stopped teasing her if he could see the blush on her face.
