There's a cycle of grief that everyone goes through after a rejection: denial, bargaining, anger, straight-up insulting, and, if you're lucky, acceptance. 

Redditor LucidDreamCatcher had the misfortune of a creepy dude messaging her through the whole cycle.​ Without seeing the irony, the dude sent 19 (!!!) messages before saying "I know what no means hoe," only to later say that she should be flattered that he asked at all, and how dare she tempt him by posting a pic.
