Clanker

A slang word used among Mormon missionaries which defines someone who strongly adheres to the Missionary standards and corrects others in a holier-than-thou attitude. This term does not call people who adhere to the Missionary Standards alone.

Comp: Hey, where were you? You know the handbook says we're supposed to be in sight and hearing of each other.
You: Alright. (under your breath) Clanker.

Tiwi

A term that refers to the system inside of a Mormon church-owned vehicle. It is required that it stay plugged into the vehicle at all times to correctly log missionaries' miles and infractions, as well as remind them if they are about to incur an infraction.

"Dude, my tiwi won't stop telling me 'aggressive.'"
"Well, maybe you should stop doing that!"

Wallhopper

A Mexican racial slur. After Trump began building the Mexican border wall, the foreigners began jumping over it.

"Those damn wallhoppers!"
"Careful, they'll send their cartel after you."
