“What is meant about his back?”
I’m guessing there was a kamasutra-like sexual position that didn’t go as intended, resulting in instant back pain for Andrew Gillum. When Andrew screamed “Get off, get off!”....he wasn’t talking about his partner’s desired sexual completion.
"Of course I'm into threesomes. Isn't every Democrat?"
See the “street” reference to “baby’s got back”.... in rap ola pseudo music land. A uh, “cultural” preference, usually directed at women, but “crossing over” from the confused males who were uh... at a minimum what used to be called “latency boys” in the old psychological/ psychiatry language of the i guess Freudians. Nancy boys in Brit street gang lingo of the 50’s .... they like the bungo bungole.
