Replacement of any insult in the English language: idiot, moron, dumbass, jerk, douche, shithead, etc. Unflattering reference to Pete Wentz, bassist of Fall Out Boy. Coined by posters at the popular blog The Hater, featured on The Onion AV Club.
"Oh my god, Sarah, you forgot to do the homework *again*? You're such a Wentz."

Can also be a verb ("He really Wentzed it up this time!") or an adjective ("That girl is such a Wentz-face!").

Get the wentz mug.
A whiny little nothing master; a bitchboy; an utterly fatuous dickweed who suggests that they simply want to live their life and not be criticised all the while shoving there inconsequential and generally annoying presence up everyone's ass, ad nauseum.

Although he/she professes the opposite, a wentz thinks he/she is a special, delicate flower that wilts when unloved.
Guy: My brother is a total wentz
Girl: Oh my God, that is awful.
Guy: Yeah, he bitches and cries nonstop; also, he regularily urinates himself when challenged. In short, His sexual identity is malformed and he therefore suffers many emotional and egotistical neuroses.
Girl: Where does he go to school again?
Guy: Stanford, obviously.

The modern wentzing began on twitter, summer 2013; it became a huge fad in the Fall Out Boy fandom. Wentzing is when someone tweets a misleading caption with a photo attached, and when the victim opens that tweet, they get an eyeful of Pete Wentz's (leaked) nudes. The meaning of this is to not only shock the victim, but (hopefully) people around, near, or next to the victim will also get wentzed, and accidentally wentzing your grandma has got to come with a good reaction. This spread like wildfire and now everyone, even famous people, know what wentzing is. People such as Patrick Stump and Dan Howell have been wentzed.
