Repentagram
A symbol made by the heaviest Christian band ever, Impending Doom. Often confused with a pentagram at first glance; it is really a combination of the latter word and 'repent'. It vaguely resembles a cross within, yet; it was all made up as a joke. See Goreship.
Mother: Why does that guy have a pentagram on his shirt??!!??
Son: Relax, mom. It's a REPENTagram.
