Definition: Trucker hats are mesh caps (sort of like a baseball cap but stiffer and with a higher crown) collected by truck drivers from various stops along their driving routes, but after "Punk'd" cutie Ashton began sporting them 24-7, a serious craze started. Somehow these hats are so kitschy, they're cool. Many stores and designers sell their own take on this trend, but you can pick up an original at any gas station for half the price.

Pronunciation: truck-er hat
