Sometimes the word ogly is not enough to stress how ugly the person is, so the term OOOOgly can be used with a capital 'O' and by definition this means the persons fully an ogre and fully ugly, i.e. the ULTIMATE insult for an ugly person.
Mate 2: Don't you mean the OOOOgliest bird in the world with a capital OOOOgly!!!
Simy: Oh my daiz, that bird is ogly.
