It's a general insult towards southerns. In 1961 during the referendum on constitution massive ballot cast fraud across the board resulted in a town called Wanlaweyn to pull more vote than Mogadishu and Hargeisa. 100% approve rate, the only in the entire country.
Yes I know, the insult is targeted at the SYL government for rigging the ballot in Wanlaweyne town.
It received more votes cast than the entirety of Somaliland.
The SYL government was dominated by reer PL.
