Random words

[zhirafov-nyet.livejournal.com]

I've seen & heard some words lately for which I can't find the meanings. The first is «чё», which is just plain weird-looking. The second is «лажаю», which seems to be a verb. And, conveniently enough, they both occur in one line of a song («Пародия на проект», a really strange song stuck on at the end of Tanya Bulanova's album «Мой сон»). The line: «Чё то я лажаю капельку». Also, I've seen «чё» in people's LJ entries too. And now that I think about it, what does the (probably unrelated) word «че» mean?

EDIT: (For the sake of saving time & being lazy) Thanks, everyone!
