マンコビッチ == MA-N-KO-BI-CCHI

manko is slang for vagina. bicchi is borrowed from English "bitch", but is used more like English "slut"

That said, those Russians could've used ヴィッチ WI-CCHI, such as in https://ja.wikipedia.org/wiki/%E3%82%B8%E3%83%A7%E3%83%B3%E3... So why does Mankovich use BI but Markovich uses WI ? Because expecting katakana spellings to make sense is already too much to ask for, let along expecting them to be consistent.

(Bonus: sandwich uses neither BI nor WI. It uses I. SA-N-DO-I-CCHI)

I wonder if Russia's ever offered Japan a better, more central location for their embassy. In Yakimanka district.
