What does MCM stand for on Facebook?

As of 2014, MCM is a social media slang term that means “man crush Monday” or “man candy Monday.” MCM is generally used in a light-hearted way by users posting pictures of males they find attractive.

WCW is the female version of MCM and stands for “woman crush Wednesday.” MCM and WCW are considered social media mini holidays, and users typically participate by posting a picture of a famous celebrity they think is good-looking. Some users prefer to post pictures related to brands or themes they enjoy, such as the Starbucks mermaid. MCM is also used less frequently to refer to the band Mad Capsule Markets.
