Ironical nickname of Saint-Petersburg (where the kerb is commonly called поребрик instead of бордюр).
Правильно заметил: поребрия не московия. В московии бензин стоит на 2 рубля дороже, чем в Московской области.
Rightly noted: Petersburg is not Muscovy. In Muscovy, gasoline costs 2 rubles more than in the Moscow region.
