Preference versus compulsion: neat people enjoy order and can skip it; OCD is intrusive, unwanted thoughts plus rituals done to relieve anxiety - time-consuming, distressing, and not chosen.
The person with OCD usually knows the fear makes no sense and performs the ritual anyway, because skipping it produces real distress and the relief lasts minutes. NIMH's markers: time-consuming symptoms - an hour-plus a day is a common yardstick - that interfere with daily life. It is very treatable with ERP therapy and SSRIs.

Common questions
What is the difference between OCD and being neat?
The difference is choice and suffering. Being neat is a preference: order feels good, mess feels mildly annoying, and you can leave the dishes in the sink without your brain sounding an alarm. OCD is a disorder: intrusive, unwanted thoughts that feel like threats, and rituals performed to neutralize the anxiety - not for satisfaction. The person with OCD typically knows the fear makes no sense and performs the ritual anyway, because skipping it produces real distress, and the ritual buys only minutes of relief before the loop restarts. NIMH's markers are time and interference: symptoms that are time-consuming - an hour-plus a day is the common yardstick - and that cause significant distress or interfere with daily life. A tidy person whose house is ordered and whose life is fine is tidy; someone who cannot leave for work until the stove is checked eleven times is describing OCD. Using "OCD" as slang for organized trivializes a real and very treatable condition - exposure and response prevention therapy and SSRIs help most patients.
