The loss of an erection or overall sexual arousal due to the sudden visual of a hideous looking individual. Usually occurs when trolling through craigslist personals section. Should be accompanied by a "wah waah" horn sound in the background.
"Ugh, I was trolling the Craigslist casual encounters, clicked on a chicks ad, took one look at her, and had immediate bone droop."
