Word to describe dumbass teenagers who act like they know everything about a topic when they have done no research at all.

Also applies to grown adults that are mentally still in high school.
This youngtard from the college was trying to tell me a gun ban would have stopped the massacre in Las Vegas.

The man at the desk claimed the White House is being run by white supremacists. Sounds like something a youngtard would say.

..because he was crying about Trump's tweet at work. I dont want a youngtard on my team!
