This 'tickle bumps' is a line from the movie 'Frozen.' A little girl said that phase while she and her sister were going down a slide of snow together joyfully. I looked it up, but it didn't really work. Would you tell me what it means?
It's not really a common phrase; in the movie, it's what the little girl calls a bump in the snow that makes her tummy "tickle," like riding on a roller coaster does. As Utsan said, the title of the movie is Frozen; "The Snow Queen" is the Hans Christian Anderson story it is loosely based on.
