The 32-year-old singer, who gave birth Monday, took to Twitter to explain that each of the characters in the baby’s bizarre name represents something special to the couple.
She then went on to explain that the next symbol in her son’s name was inspired by fantastical elves.
‘A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent,’ the star stated.
She also added that A additionally stands for ‘Archangel’, ‘her favorite song’.
Grimes then ended her odd tweet by sharing emojis of crossed swords and a mouse – writing ‘Metal rat’.
