Gruntry

The sinister fusion of country and grunge embodying the unique sound of Seattle. See Seattle local band Red Heart Alarm, the first named "gruntry" band of the NW.

Grunty Face 

A fake "Grunt" Face that people make to "Act" like they are helping you move, or lift something.
When you ask a friend to help you move your couch, but instead of actually helping, they put on the "Grunty Face" and just look like they are lifting something, and they are of no help.

Comon Derek, Help me lift, dont pull a grunty face on me.
