A kick ass name. It is commonly used, well... only used,as a creative name for video game customizable items. Only things that kick ass deserve to be called by the name of Won Buu. It may also be used repeatedly to confuse opponents.

In no-limit poker, to bet all of your chips as a sign of total confidence in your hand.

If you have a very good hand, go all-in to win the maximum number of chips or to scare off mediocre hands so they won't catch the cards they need to beat yours. If you have a bad hand, you can bluff by going all-in and hope everyone folds.

WON already is replaced by Steam. Won stands for the World Opponent Network, which was the system that channeled multiplayer for half-life and all hl mods since hl was released up to the end of the summer of 2004, when WON was no longer in service and all multiplayer was transferred over to Steam.

I still remember WON to be more complicated than Steam, but it had its ups, like whenever something happened or something was typed, you would see it in console instantly,
and whenever you would join a server, it would show you the console screen and you could have something to read instead of a black screen with a loading bar that Steam gives you. You also didn't need to be logged into any program to access WON (I'm talking about you,STEAM) and although all your mods were not organized into a list, you could just access them from your desktop. Part of me still misses WON, but WHY?

So if you say someone is all bark, you're telling people to disregard the warnings or threats of that person, because he or she won't actually follow through with them.
