It is thought to mean as "wow" but is in fact a way to say "whew" in Filipino. Mainly used in game chat because it is faster to type than "whew" or "phew". It is also a form of txtspk.

Often used as a general derogatory term to pertain to a certain subset of gamers but can also be added to annoy others. Usually used in combination with some Filipino words for hilarity.

Widely used by Filipino gamers to express frustration. It was first coined in a 2007 casual rhythm-matching online game called O2JAM by a username "superwax123.” The word "wew" itself was originally intended to replace the expression "wow" since "w" and "e" keys are very near to each other.
