The texting "convo of origin" of the term:
Friend 1: Walking to Georgetown U library now. Happened upon attractive-ass men drinking and eating outside in an exposed outdoor patio thing. Was so tempted to awkwardly sidle my ass over and say hi.
Friend 2: Please describe their attractiveness to me.
Friend 1: Preppy white attractive. Just some bros chilling, enjoying their Saturday.
Friend 2: I love that you live so close to the prepicenter.
