MLG Pro

MLG stands for major league gaming. This is pretty cool. An MLG Pro, however, is someone who blows off playing Xbox Live with their real friends to play with other MLG Pros, who are all in the MLG, but they have no idea who they are in real life. They also take games way to seriously, and sap the fun out of playing with them. According to MLG Pros, "video games are not for fun. They are serious business". One way to counter an MLG Pro is to simply leave the game, or do stupid things to screw it up.
When I was playing Gears Of War 2 with my friend, who is an MLG Pro, he got mad when I said I had to go eat dinner and that I might do something else or play a different game afterwards. Then, when I decided to play with him again, he said no because he was playing with his other MLG Pro "friends".

Pro Deo

A Human action taken only for the sake of and in the name of G-d, being literally "For G-d", usually one that is on behalf of other persons in need of urgent aid--such as only those who take their cause in name of G-d will provide. It is aid offered in most ernest faith and brotherhood, never for the least of material gain of any kind.
A famous example: the lawyer who takes the case of the accused man, downtrodden and racially opressed, in the novel "Cry the Beloved Country" as Pro Deo; 'For G-d'. Other examples are possible, but the phrase has fallen out of fashion--it should, perhaps, be revived.
