Poking your nose into other peoples business

Hello,

I would like to know about the expessions or phrases similar to this one: poking your nose into other peoples business! It is often said by people although with different options. Is there an original phrase like this?

Not phrases but:
busybody
kibitzer
gossipmonger
buttinsky
nosy-parker
yenta
quidnunc

I AM impressed. I never knew that another word for "snooping around" or "sticking your nose where it doesn't belong" was quidnunckery. Until now. (Actually, quidnunckery is more like simple gossip-mongering, but close enough.)Thanks, Bruce. SS
