BSO

Literally “Bright & Shiny Object,” this is an old internet term meaning current obsession or fandom.

Sometimes with the variations of “Bight Shiny Obsession”, “Beloved Slash Object”, “Beautiful Sex Object”, etc. in Web 1.0 fandom spaces.

The Roman Empire is my current BSO

English Twins

Siblings born on the same day, but one (or sometimes two) years apart.

Possibly a play on the idea of "Irish Twins"

The brother and sister share a birthday; they're English Twins.
