Mantel Season in a fictional season, created by women, to guilt their husband's into building extra large mantels to decorate. Once the mantel is built, they are extremely over decorated, so the women can flood
social media with pictures of their mantels. This causes
other women who have guilted their husband's into building expensive, oversized mantels, in the name of "mantel season", to overwhelmingly show support, so they can then guilt their husband's for not showing support for "such an extremely important
celebration that they were robbed of up until that point." Mostly celebrated by "Karens," but also celebrated by the "Y" variation as Karyn.
"(Enter any name like 'Chad'), you have robbed our family of the
enjoyment of mantel season for too long. I demand you to build one, or I
want to talk to a
manager."
