cheavesdrop 

when you catch a glimpse - (deliberately or not) of someone's online chat. Sometimes they have been discussing you. Usually in a bad way.

1. My sister Mary had been chatting to her bff and forgot to log
off when she went to the bathroom. I cheavesdropped and saw she had been dissing me!

2. At the net cafe I did a cheavesdrop on the guy next to me and saw his romantic conversation with his lover

cleavesdropping 

Positioning oneself so close to a female or group of females, that you can actually peer deep down into their cleavage!

Last night we were clubbing and cleavesdropping all the fine women sporting hot summer tees. So fine!

To covertly look at a womans cleavage without her knowledge. Derived from 'cleavage' and 'eavesdrop'.

"Whoa, look at the rack on that one!"
'Yeah, I've been cleavesdropping on her all night!'
