mind's nose
When a odor lingers with you long after you experience it. Usually a foul smell.
Dude, I changed that poopy diaper hours ago and it's still in my mind's nose!
mind-controlling nose gnome
A once considered mythical creature that lives in the oversized and distracting wart on the end of a nose. Only a wart gnome attached to a waron has the ability for mind control. The gnome often is perverse and has a one-track objective. The gnome has the appearance of a racecar driver and controlls the host with a steering wheel.
The waron walked up behind me and then the mind-controlling nose gnome ordered him to put his hands on my body. Gross!
