An amazing song by pianist/vocalist/percussionist/guitarist Regina Spektor. In this case, BYOS is an acronym referring to Bring Your Own Shovel. It is a play on "Bring Your Own Sh*t" in that the song is about receiving an invitation stating to "bring your own shovel and shovel up the mess."
My invitation said bring your own shovel; I brought my own shovel, BYOS.
"I love the song BYOS by Regina Spektor. "
