Someone who stares at their cell phone while actually doing nothing with it or randomly scrolling menus. Usually done to avoid social situations, to look busy or to show off phoneiPhone.
Tom goes into iPoseur mode when he is the first to arrive at Happy Hour after work.
When someone tries to make it look like they own an Ipod when they dont. An Iposer puts ipod headphones in their ears and puts the end of the wire in their pocket making it look like they are listening to an Ipod. An Iposer will ussually shake their head to make it look like they are actually listening to music.
"Nima was wearing Ipod headphones but there was nothing connected to the other side of the wire... what an Iposer!"
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...."
