Coup d'tard 

An attempt to overthrow a duly elected government that dramatically fails due to incompetence and stupidity.

On January 6th, 2021 President Donald Trump incited his supporters to storm the capital but ultimately it was just a coup d'tard.

Z-Tard 

A Russian Fascist, specifically the type you would see sporting a capital Z in their bios online or wearing it IRL. This stems from the 2022 Russian invasion of Ukraine, as many units were spotted with it painted on their vehicles, with the letter subsequently becoming a pro-war symbol on the Russian homefront and among really, really delusional anti-west westerners online.

Person 1: Bro, look at this video of all these bitchless individuals waving pro-war banners in Russia!
Person 2: Z-Tards being cucks as usual lol

ed-tard

Stemming from Edric, this word commonly describes one who is stupid, ugly, gay and a loser. This insult is heard rarely but when used can cause serious mental effect on the recipient due to its very harsh meaning. A large piece of crap or coffee stain may also be seen on the recipients face and it is deadly.

Elden: Hey I got an F! Now lets go check out some guys!
Joe: Dude!!! You are such an ed-tard, don't talk to me!!

You are so ed-tarded!

adult-tard 

An adult who does ridiculosly stupid things as a way of showing their maturity. Eg; when a little bird finds it's way into a classroom of fifth graders, and adult-tard would be the first one to catch it and call animal protection, instead of letting it fly away. Making oddly stupid rules and descisions is another habit of adult-tards.

At my school, they caught someone smoking in a restroom stall and the adult-tard principle made a rule against using the bathroom.
(true adult-tard moment)
