Card Crusher, also known as the rude dude or Zoomjap is an old-as-the-internet-itself 4chan /a/ meme, consisting of a series of strips based on Professor Himonya (碑文谷教授 in moonspeak), a rude Professor of Linguistics from the University of Tokyo (who apparently is an expert on making people uncomfortable), who goes on Japanese TV and creates lulz by insulting various presenters. It began when a certain /a/sshole posted a YouTube link of him being interviewed.
The twist of the video happens when Professor Himonya gives the female interviewer a business card and asks her to pretend it's hers. She then presents the business card back to him; he looks at it, smiles, and then proceeds to crush it in his fist and hold it to her face, whilst maintaining a pose and goofy facial expression. In Japan, business cards are serious business, so doing this is the eleven version of raping someone else's family pet in front of them.
