Mithrasmas
Blend of Mithras + Christmas.
The story
In reference to one Roman Dies Natalis Solis Invicti associated with December 25 and unrelated to Mithraism. Sol Invictus was also conflated with or used as an epithet of Mithras, from where the confused misidentification arose. Apparently coined by Gwendolyn MacEwen.
Today it means
name Christmas (Christian or secular holiday held on December 25), presented as linked to Mithras
