“Chris won’t be making it out to Thursdayruns for a while, because he is an IPOS”
Cliques who form solely around the ownership of iPhones. Race, sex, or religion play no part in the formation of iPosses and the main topic of discussion in said posse will primarily focus on the features and apps of iPhones.
Note: iPosses may or may not act snobby towards iPhony's and/or non-Iphone owners. It all depends on the individual.
After John got the iPhone he was immediately accepted into the local chapter of the iPosse at his school.
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 phone iPhone.
Tom goes into iPoseur mode when he is the first to arrive at Happy Hour after work.
