Leave means whatever you want it to mean. I see too many people arguing online that it means a no deal Brexit. No it doesn't.
Before the referendum I went to a legal seminar where several options were set out - Norway deal, Turkey deal, Switzerland deal, WTO. No deal wasn't mentioned, presumably nobody thought we'd be that stupid at that point.
There are lots of leavers out there who dislike the political union we have now but were happy with the Common Market as it was - so presumably a Turkey type customs union deal would suit them.
Switzerland is too complicated and the EU ruled that out.
WTO is an option but as has been pointed out on many occasions, only one country in the world functions purely on WTO rules and anyway there is more to cooperation with the EU than trade.
EEA keeps us close to the EU but is expensive and means we keep freedom of movement (though we do have control and can send people home after 3 months if they don't have a job - our choice not to at the moment).
Lots of options, lot of interpretations of "leave". Pros and cons to all (except no deal which has no pros at all).
I'm lukewarm on another referendum, I am not sure Remain would win, and it would also provide a precedent for another indyref in Scotland. Politicians got us into this, they can get us out.
