Like a paparazzi, but only takes photos at appropriate times instead of sneaking up and taking pics when people least expect it.
Dan: This one guy went right up to Jessica Simpson and asked kindly to take a few pics.
Dave: Man, what a properazzi.
Noun: Real estate's google
Verb: the easiest way to search for a place to live, requiring no physical effort aside from typing.
Last night I properazzied for 5 hours and still can't find anything I can afford. Fucking New York!
