I was watching Hetalia and Italy and Germany did a pinky promise, and then Italy asked "Where did the pinky swear come from?" And then Germany said "From Japan, but don't ever Elephant swear."
What the heck does that mean? lol XD
Answer on Hetalia, What does it mean to Elephant Swear?
It's "pinky swearing" with your penis. Least, that's what I've been told.
