When Russia is upset, he uses the chant "KolKolKol" to threaten and frighten others into submission. However, there has been speculation that there are other possible meanings for 'kol' than those involving kolkhoz:
Tzar Ivan The Terrible's favorite way to deal with disobedience was impaling. 'To impale', pronounced in Russian as сажать на кол (sazhat' na kol), or just на кол 'na kol' is easily understood. So, Russia is possibly trying to intimidate people by the threat of impalement, although he is saying the noun 'kol' (which means 'stake', in this context being thrust towards a person).
There is also the possibility that Russia could be issuing a warning to others. 'Kolokol' means 'bell' in Russian, and 'kol' is often used as an onomatopoeia in Russian for the tolling of a bell, a centuries-old designation of approaching danger.
Another interpretation offered by the Japanese fandom is that "kolkolkol" is "korukorukoru", which sounds similar to "korosu", the Japanese word referring to killing.
Another interpretation offered by the Russian fandom is that "kolkolkol" means "sending to kolchoz".
