n.
a mysterious aura of loneliness you feel in certain places; the palpable weight of all the lonely people secretly holed up in their houses and apartments, with a flickering blue glow cast up on their walls—so many of whom might just want someone to talk to, or just want to feel needed, and could be that for each other if only they could somehow connect.
Short for “All the lonely people,” from the song “Eleanor Rigby” by the Beatles. Pronounced “al-uh-pee.”
