When two people or characters, who have romantically liked eachother for ages but hasnt admitted it to themselves or eachother but everyone knows, get together and it becomes weird and awkward and overall horrifying to all who happen to witness it and they act all corny with eachother. Much like a certain episode of the cartoon Kim Possible where Kim stops an evil guy from blowing up a planet or something and at the end of that cursed episode Kim tells Ron that he's "out of this world". *shudder*
I almost vomited when Ron and Hermione pulled an out of this world at the end of the 7th HP book.
Oh dear God please tell me Ranma and Akane wont start pulling an out of this world. I think I'd be scarred for life.
