When your taking a piss in a urinal and there are plenty of urinals to either side of you and someone walks in and starts pissing in the urinal right next to you and making you feel really uncomfortable, they are being a nosy neighbor. They can also make it even worse by making small talk with you, or even go so far as taking a peek at your junk.

Beauford: Oh that sucks man.
