Help!!

Ok; so I had a weird moment this week where someone posted a pic of a king cake and asked ‘wtf is up with this? ‘
So I orginally thought it was like a joke post; best of tumblr and all that bs.
But no. Apparently no one where I live knows anything about king cakes, jazz, or hurricane parties.
Help me out please WordPress? How widespread is the knowledge or lack thereof? ?
