An abbreviation for Christmas, from the Greek spelling of Christ, the first letter of which was chi ("X").

Contrary to popular belief, the X in X-Mas was not made up by the secular heathens in California (no attack intended). X-Mas was a shorter version of Christmas, first used in Europe around the 1500s. In Greek, Christ's name started with an X, Xristos. Thus, it is literally, "Christ-mas", or "Christ's Mass".

Xtreme Martial Arts

Usually a combination of the most aesthetically pleasing moves from multiple martial arts, strongly based off of wushu and tae-kwon-do 'trick moves' (see tricking). Many of these tricks are very difficult to pull off and require extensive training and 'set-ups' such as the illusion, butterfly kick, and the j-step. Some XMA artists are Steve Terada, Tony Jaa, and John Eigo.

Xmas quite literally means Christmas. The 'X' is a representative of the Greek symbol chi which means Christ. There for Xmas stands for Christmas and is just a short hand version of writing Christmas, and in no way removes the religious connotation of the holiday.

'Xmas' is another way saying 'Chirstmas' which is supposed to be more secular than the latter. However, the 'X' part of 'xmas' was used by early Chirstians to identify themselves as a follower of Christ. By marking an 'X', they signified either a safe house, gathering place, or the like. X is the character for the Greek letter "Chi" which was the first letter of Jesus' name in Greek.

To say that xmas may have no religious value today is perhaps true, but ironic becasue xmas and Chirstmas are literally one in the same.

This is an abreviation of the word christmas. Generally used by people who are to god damn lazy to write the full word.

It just means Christmas. It's easier to write if you put an X. No one is trying to take the precious CHRIST out of Christmas. For God's sake, lighten up. Your religion's not going to die because we say Xmas instead of Christmas.
