What instantly kills the vibe at a party?

Whiny ass, entitled liberals.

A gun.

Talking about serious political stuff - the Gulf War, Stormin 'Norman, the US coup last week in Latin America, the WMDs lie, the unlivable, unsustainable suburbs, the transit problem in US cities, falling purchasing power, privatized housing, falling lifespan and poor US educational performance.
The hippies don't want serious to interrupt the fake fun on the weekend, or the werkkk they do all week for NATO!

I hate when some scruffy lad whips out his acoustic guitar

No babes and drinks

Politics

An implosion, no matter how predictable. 🙊

That noise of plugging a beat box in

The loud mouth shows up

Democrats

Drama

Trumpers
