You must be really retarded to insult someone, because he doesn't speak english very well. For most of people english is their second or even third language and people like you, who can only speak english have no right to laugh at them.
Actually we have 4 langueges in Ukraine.
1. Galician - west Ukraine.
2. Ukrainin - nothern and central Ukraine.
3. Surzhyk (mix of russian and ukrainian) - southern, central and eastern Ukraine.
4. Ukrainian russian - southern and eastern Ukraine (+kyiv/kiev)
