👉 HDHM stands for High Definition Miniaturised Hologram, which is basically a fancy way of saying a super duper detailed 3D picture that looks like it came straight out of a sci-fi movie but instead of aliens, it's your neighbor's cat in a spacesuit. Imagine if every time you opened a box of candy, it was an HDHM of a giant chocolate dragon with a side of pickle - that's what HDHM is for, but instead of candy, it's techy and it's a bit creepy.
Edgy example sentence: "I just ordered the HDHM of my life - a holographic replica of my late grandpa playing rock 'n' roll on a ukulele, complete with a side of existential dread."
