bung finger 

The accidental one two punch of picking your ass and then your nose. Usually happens on a long couch surf where you ass pick and then an hour later try for some nose gold. The scent of musty chili ring gets ingrained in your nose and the decision to sniff and stay or wash and pray must be made.

Dude, i accidentally bung fingered last night . I had to flush by booger maker with vicks to kill the funk.
