Matt threw a party. Strange enough.

At some point in the night, I came to the realization that I was at "that" party. You know what I mean here?  At every party you realize that you at some kind of party, and someone says something that is completely cool and acceptable, but only at "that" kind of party.

I think what was said was the word "argayle." 

Matt threw the kind of party where the word "argaryle" was just great.
