delete that Yahoo answer it is totally weird.
the word had three syllables, viz
бу pronounced like what a ghost says -- boo!
кре rolled R, which is palatalized (slight y-glide) before the letter e pronounced like the e in "yet"
ев pronounced like yeff sounds like Jeff with a y-glide as in "yet"
The middle syllable is louder, i.e., it is the stressed syllable.
There are some slight differences in real pronunciation that what I can express here
