The Dictionary of Obscure Sorrows?
I love this one:
astrophen. a hypothetical conversation that you compulsively play out in your head—a crisp analysis, a cathartic dialogue, a devastating comeback—which serves as a kind of psychological batting cage where you can connect more deeply with people than in the small ball of everyday life, which is a frustratingly cautious game of change-up pitches, sacrifice bunts, and intentional walks.
And then there's this, for when you're having that hypothetical conversation and realize it's not playing out entirely in your head.
lalalalian. the realization while talking to yourself that someone else is within earshot, which leads you to crossfade into mumbled singing, an auditory sleight of hand that distracts the audience from the exposed platform under your persona while you prepare to saw your confidence in half.
Long live the Internet.
