Pro (ConceptClass, 4)
From Compile Worlds
A pro is one who has shown a high amount of proficiency in an area. When pros do something, it is usually filled with a large amount of awesome, win, and/or total ownage. In most cases, pros portray themselves as modest people. Of course, we all know that modesty is a lie, and that they only do this to cover up their feelings of superiority.
The pro meme was coined a very long time ago on PSOBB, and carried over when S2PID joined Puyo Nexus and later Kumizone (sorry, what? *looks at Special:Contributions/S2PID*... Oh, he did... purely to make this page, over a year ago). Originally it was used as a sarcastic remark when someone fucks up, but it has mutated into a more literal remark said when something awesome happens.
