Wikipedia:Wikipuffery

The multicoloured tail feathers look impressive when they're puffed up, but without them, the peacock looks (almost) just like an ordinary bird.
Not so impressive now, is it?
Well, you get the point...

Wikipuffery is the puffing of a subject or the addition of praise-filled adjectives and claims. They may be there to exaggerate the notability of the article subject to avoid deletion of the article. Examples include use of adjectives such as "famous", "notable", "best known", "award-winning", "acclaimed", or "influential", detailed listings of minor biographical details (including complete lists of anything related to the person or topic), and lead paragraphs that proclaim the superiority of the subject.
