"Stupid" and "dumb" are ableist terms. Put the work in to remove them from your vocabulary.
Such words, because they are ableist, are weaponized by abusers to control and break people. They are sharp words. Tread carefully.
Not using ableism as a basis for your insults means you get to get creative:
- Flaming turd from the festering pit of hell- Morally corrupt leech- Blood-thirsty demon- Overgrown mosquito
Or you can go more typical:
- Asshole- Jackass
