Originating from a 4chan post in late 2016, the 'Notices Bulge / OwO What's This?' meme parodies stereotypical furry roleplay dialogue. The phrase became a viral copypasta, characterized by its 'cutesy' yet suggestive tone and the use of the 'OwO' emoticon, representing wide-eyed surprise. It typically depicts a character reacting to a perceived protrusion (the 'bulge') with exaggerated curiosity. Over time, the meme evolved beyond its furry subculture origins into a general internet shorthand for any situation involving an unexpected discovery or uncomfortable observation, often used ironically or for shock value in shitposting communities.
