Indo-European for Indo-European

Indo-European for Indo-European

I was wondering (again with the wondering!), if whether there was
any PIE term that was common to all (or most) Indo-European
descendants; or possibly a reconstructed term that would fit a
plausible PIE description for themselves. I was writing an article
about my own ethnic origins when I couldn't think of a "poetic" term
that could denote IEs. Saying "the Indo-Europeans" doesn't sound
poetic -- it's too scientific. "Aryan" just sounds
too "elitist", "The Fair-Eyes" too misleading; but "The People"
could be possible since every society referred themselves as "The
Only People". Well, I'm not a linguist so I don't know what would be
the PIE equivalent for "The People" --> something connected to
teuta, tuatha, theudisko or something. Basta something that is
unique to the IEs --> Horse-masters or Cow-people for example. horse
= ekwos?, cow = ???
Help please,

Peace out,
