I'm unsure whether my question is on-topic, but I learn Russian and got really curious when reading a Radio France Internationale article of September 2021 written in Russian and quoting a Russian political scientist, Valery Solovey, as saying:
Деньги он может получить, конечно, только в России. И это главное объяснение визитов Лукашенко. В Кремле его считают хитрым крестьянином, Владимир Путин дал ему прозвище „Картофельный лось“. Путин иногда даже любуется тем, с какой крестьянской хитростью Лукашенко обходит его, мастера геополитических комбинаций. Я нисколько не шучу. Лукашенко раздражает Путина, и одновременно у российского президента нет альтернативы. Он не может заменить Лукашенко, а Путин нуждается в каком-то геополитическом успехе.
My translation:
He can get money only in Russia, of course. And that's the main explanation of Lukashenko's visits. The Kremlin considers him a cunning peasant; Vladimir Putin coined a nickname for Lukashenko - Potato Moose. Sometimes Putin even admires the peasant trickery with which Lukashenko successfully deals with him, a geopolitical grandmaster. I'm not kidding at all. Lukashenko annoys Putin, but Russia's president doesn't have any alternative. He can't replace Lukashenko and needs some geopolitical success.
So, why Potato Moose? What could Lukashenko have to do with moose and potatoes?
The quoted text creates an impression that this bizarre nickname might be related to Lukashenko being seen as a cunning peasant, but what could be the logic of this relation if it exists?
I'm really puzzled and humbly hope that SE users interested in politics can shed some light.
