The adoption of trends through the use of props, mostly bought together, such as hoodies, knit brim caps and jeans- or leggings, UGGS and earflap hats.

"Hey man, with that new hat, jeans and hoodie you got on, it looks like you got all Trend-O-Matic at Target today."
"Oakland has changed, man. A bunch of trendsters
who moved from SF when the economy tanked. Lot's of hoodies, tattoos and baby strollers. This used to be a totally cool neighborhood. Now it's Trend-O-Matic."
