What it actually means
Boo’d up describes being coupled up, often with a warm, affectionate emphasis. It comes from boo, a long-standing pet name for a romantic partner. Ella Mai’s 2018 R&B hit Boo’d Up helped make the phrase especially visible to a broad audience, but did not create the underlying boo vocabulary.
