Market makers do this as a free way to cover delta risk in that direction. If you have +100 delta, selling 100 "units" (way out of the money options) is a nice way and doesn't carry any other greeks.
I've seen speculators do this, but they're playing with fire. I've seen an investor risk 9 digits to pick up $50k a minute before strike expiration, not realizing that the actual settlement is the next day (so adversarial events can still happen).
These tail risks are impossible to predict, and volatility of volatility of these events is incredibly high. So your expected value is better to think of as a "very broad range with a positive mean" - are you comfortable with this?
... generally that refers to the strategy of writing (far) OTM options.
Like: the Dow is currently trading at about $49.44; and the bid/ask on a Nov 18th put with a strike of $40.00 last traded at $0.04. So you can write 25,000 of those and get $1,000 in premium. Those are the pennies.
You can't lose any money unless the Dow actually below $40.00 because those options will expire worthless. However, if the Dow goes to $39.00 ... then you'll be on the hook for $25,000. That's the steamroller.
