Hyperfine refers to someone who, when asked how they are/how they feel,
always says that they’re
fine even if they’re not.
When someone uses the phrase, “I’m
fine.” continuously to the point that their answer is predictable, they would be considered hyperfine.
“Have you
seen Stacy today? She looked upset.”
“Yeah, I asked her if she was okay and she
said she was
fine.”
“Well, duh. Stacy’s hyperfine. Something is definitely bothering her.”
