person at home: Dude where were you all this time? you said you'd be here an hour ago.
Person at the door: Don't even get me started! I was all on time until I got blocked by this pavement blob in front of me who had her headphones on and it sure wasn't an exercise tape she was listening to!!!
person at home: Yeah I totally hate pavement blobs
Person at the door: Me too, so quit being a door blob and let me in!!
The motion some women and mostly soul divas make with their necks when giving their men attitude. Not an easily accomplished motion involving moving the head and neck in opposite directions.
