Cynthiosis

If someone I has been diagnosed with “cynthiosis”, it means that they act on instinct, without thinking decisions through.

Wife: Babe, can you please vacuum the living room?

Husband: Yes, but the vacuum doesn’t turn on!

Wife: Really Cynthia? It’s because it’s not connected yet!

Husband: sorry babe, I didn’t notice it since my cynthiosis has been acting up lately.
