Hyperbole: An exaggerated statement not meant literally, for emphasis or humor.
"The amusement park was so much fun it ripped the space-time continuum. I rode every coaster seventeen times in three seconds, ate a cotton candy cloud the size of a cumulonimbus, won a stuffed bear big enough to chaperone a kindergarten class, and laughed so hard my ancestors felt it in their bones. Best day in the history of the multiverse."
This exaggerates time, quantity, size, and impact for comic effect.
