Get a NERTS mug for your Uncle Manafort.
A swear replacer. Don't say a swear, use "nert". Teachers and parents don't know what it means so it makes it a way to beat the system.
My teacher was pissing me off and I screamed "nert" and she didn't know what it meant so I got away with it.

Get a Nert mug for your coworker James.
A word made up by two kids named Nick and Allen in high school that is best described as an antonym to the "F" word. This word sums up incredibly stupid, yet serious, situations. Can also be used as a response to something extremely cliché.

This word evolved out of a sound made to imitate retarded people. It was more like "Ner-ner-nerrrrt!" in it's original form.
Dad: Son, you can't go to the dance until you've done all your chores!

Son: Nert...

-Used to express your feelings that something is stupid, ill-conceived, immature, or just an all around bad idea. Basically means, "That's retarded!"

-First documented use in Meridian, Idaho in the early 90's. Evolved from the sound people make to immitate mental retardation.
