The next referendum (which will be the third) has a modest chance of offering the voters an actual option, rather than an undescribed outcome, with nobody knowing what it is. It will have to do that if people are to respect it and to be able to say they are doing what the nation voted for.
So it might say "Do you want (1) to leave the EU, with no trade agreements, no agreements on movement of people and capital, no agreements on preferential terms with the EU27, border posts, customs duties, a hard border in Ireland, no right to move between EU countries, conforming to EU regulations for trade in goods and services with the EU, and no influence or power on EU regulations or laws?"
"Or do you want (2) to leave the EU, with trade agreements giving low cost, barrier-free trade in goods and services, no customs duties, an open border in Ireland, limited rights for workers to move between each others countries, conforming to EU regulations and some laws but having no say in making them, and pay a fee for access?"
"Or do you want (3) to be in the EU, with trade agreements giving low cost, no barrier-free trade in goods and services, limited rights for workers to move between each others countries, an open border in Ireland, conforming to EU regulations and having a major voice, and votes, in setting the regulations and laws, paying a membership fee and receiving EU grants, loans and subsidies?"
You'll be aware that Brextremists refuse to articulate what outcome they are offering. So Parliament will have to do it.
Parliament, which has supreme power in the UK, might decide not to offer voters option (1) on the grounds that it would be catastrophic for the nation.
The next referendum might be held next year, or it might be held in a few years time, when the Brexers will mostly not be voting. As yet, nobody knows.
Referendums held after the next one will probably have some constitutional rules added, such as "to change the status quo, at least X% of the electorate must cast valid votes, and any constitutional change must achieve at least Y% of the votes, otherwise things will remain as they are." This is quite common in countries that have referendums, since it avoids the wasteful flip-flopping between 51/49 votes and 49/51 votes.
