Here comes the neighborhood

It's what you say when you see an advertisement for a new development in a part of town that was once cool (see:low rent, dangerous, fun) and you get the hint of dread upon imagining the hoard of NPC yuppies from out of state that will inevitably fill up at least 60% of these polished turd-houses/shit-buildings. ....And all the new traffic that goes along with having several hundred new residents all trying to come and go from the area during certain times of day, in a place without the proper infrastructure to facilitate it.

Someone asks "did you see what they're gonna build down on Gay St?"

You respond (usually prefaced with a sigh that borders on a groan) "Yup. Shame... Here comes the neighborhood"
