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.

preface 

The process of screening someone who requests to add you as a friend on Facebook. Determining if they are "facebook worthy"

Some guy I really don't know keeps wanting to add me as a friend on Facebook. I did some preface work and found out he is a jerk. Saved me from defacing him later.

preficize 

verb
To add an incorrect prefix to a word to make a new word that is understandable, even though it is not necessarily a real word.

see sufficize

"un-" (opposite of, contrary to) + "fast" (characterized by quick motion, operation, or effect) = "unfast" (not a real word, but preficized so you know it means slow)
