The ultimate form of facepalm; to facepalm beyond all reasoning. So far beyond reasoning that you defy all forms logic and physical understanding. God cringes at the sight of your facepalming pwnage. To facenuke is to admit your shame for there is no greater art of recognizing failure than facenuking.
I just had to facenuke after realizingthat the same shirt I bought online, I could have gotten for cheaper at my local store.
Facepuke (face + puke) is a derogatory term for the popular social networking website Facebook, mostly used by those who think Facebook merges individuals into one homogenous grey mass, subverts users' individuality and makes them reveal private matters to their "friends" most of them the've never met in person.
A rebuke or scolding delivered via social media platforms such as Facebook. Intended by the giver to cause ebarrassment. Facebukes are characterized by their self-righteous nature, public delivery (when a private message would have been more than sufficient), lack of anonymity (as opposed to posting an anonymous comment to a blog, for example), and reluctance to engage in an intellectual debate around the topic. Usual perpetrators of the Facebuke are religious legalists looking to foist their particular idiosyncratic understandings upon others. Also known as an ebuke.
Dude, that guy who told you that you shouldn't listen to rock music on your wall totally Facebuked you.
