Remember: Whenever we say "Christmas," Christ always comes first. And whenever we say "X-mas," X comes first. Not many people know that Jesus Christ's real name is "Jesus Little." He changed His name to "Jesus X" to show that He was His own person and didn't need the white man's slave name... He was His own man. Which explains the meaning behind X-mas. It's just short for "X-Man's." Because the X-Men had superpowers... just like Jesus.
jesus x, praise be unto him, he can shoot l.a.s.e.r. beams out of his eyes.
