To some extent, it's a generational thing, like Stephanie Lynn Nicks calling herself "Stevie," or like women named Julie or Julia who have the nickname "Jules" or "Jewels," but consider that some or all of those quotes may have been fake.
Other posts have falsely claimed that Barack Obama called Michelle "Michael." For example, a video circulated on X shows Barack Obama saying: "Michael and I also want to acknowledge..." This clip, however, is misleadingly cut short. In full context, Barack Obama was referring to Michael Mullen, the then-chairman of the Joint Chiefs of Staff, not Michelle Obama.
Another misrepresented instance on Facebook features Barack Obama saying, "I walk with my husband Michael and hold hands..." Again, this clip is misleadingly edited and omits the fact that he was reading an excerpt from a message from a woman expressing gratitude for arthritis treatments and their impact on her life.
TBH, when the Fleetwood Mac album came out, I thought that Stevie was the new guy in the band who played guitar and Lindsey was the gal who sang Rhiannon.
