Acronym for "Welcome To Obama's America". Often used as a tongue-in-cheek reference to right-wing politician's criticisms of the Obama Administration. The user of this acronym (or the full phrase when speaking out loud) is normally parodying the hysteria of the far-right hype machine (which seems to purport that, due to Democracts being in power, the end of times is upon us and the apocalypse is unavoidable). This is done by "blaming" the Obama Administration for all problems that another person may encounter, regardless of how inconsequential or unrelated they may be. In most cases, the less of a chance something has to be influenced at all by politics the greater the potential for hilarity.
