Term used in countries with below freezing temperatures in a reaction to Apple's stupid Pressure Sensitive Resistive touchscreens that don't allow the use of gloved hands. Rather than take your gloves off, people with more pointed noses use the aforementioned body part to do basic functions on the phone, using the already cold nose in place of a currently warm gloved hand. Also leads to iMyopia in the long term.
"It's freezing out there. Hang on while I answer this phone using the iSmear method with my iNose...."
