-small translation "what's up"-

[red-bullet.livejournal.com]

Hey all, I'm writing a story at the moment and one character is actually trying to get away with impressing the other by dropping a line in Russian. What I need is an equivalent to "what's up?" and "Since when do you speak Russian?" if possible.

Also, if I could get it in Roman alphabet that would be greatly helpful.

Any help I would greatly appreciate. I'm really glad I found this community.
