TDS
Dissolved mineral count
TDS stands for Trump Derangement Syndrome, a dismissive term used by supporters of Donald Trump to characterize critics as irrationally obsessed with opposing him.
The accusation implies that criticism stems from psychological disturbance rather than legitimate concern: She has TDS—everything is Trump's fault to her.
The term mirrors earlier phrases like Bush Derangement Syndrome and Obama Derangement Syndrome.
TDS also has technical meanings in other contexts, including Total Dissolved Solids (a water quality measure) and Tax Deducted at Source (in Indian tax law).
