“WCW” stands for “woman crush Wednesday,” and it is a popular thing to do on social media. Users post pictures of real or made-up women they find attractive or admire.
Most of the time, the acronym WCW is used with a hashtag on Facebook, Twitter, Instagram, and other social media sites so that users can easily click on the hashtag link and see other pictures with the same tag. Many people post pictures of celebrities they like or find attractive on Wednesdays and add the hashtag. International Business Times says that WCW is like a social media holiday and gives people ideas for what to post.
