Why continue? You are the one that can’t figure out new words and terms. Do you have a learning disability? (For reference, this is what is most commonly accepted terminology these days. For anyone with a physical disability or from a disease process, “person with” followed by the disability or illness is what is used eg: person with Mamothmothman disease.)
Hope this helps, but it sounds like it won’t.
Stupid. Idiot. Sompleton. Half wit. Shit for brains. Bufoon. Moron. Mentally handicapped. Fucked in the head. Dimwit. Dullard. Ibecile. Luddite. Pin head. Slow. Thick. Mental.
