I don't have ADHD I have ADUHD haha get it I made a pun about High Definition vs Ultra High Definition although I wonder if the joke would be parsed better if I said AD4K instead

AD4K is pretty clever but isn't technically the right comparison in terms of terminology.
- HD stands for high definition, which is 720p,
- QHD stands for quality high definition which is 1440p,
- and UHD stands for ultra high definition which is 4k

but also that acronym also is close to AUDHD which is slag for the common comorbidity between autism and adhd so you'd have to explain that the joke is Attention-Deficit Ultra High Definition and not Autism (comprise with Attention) Deficit/Hyperactivity Disorder in case someone misread it but if you said it out loud maybe it wouldn't be as much of a problem
