Fluppsen 

Being an idiot. When someone says something exceptionally stupid and/or just in general acting dumb. Someone who is a "fluppsen" often acts as if he knows a lot and knows about things, but can often be proven wrong by simply questioning him/her.

The act of taking a loaf of bread, having sex with it, and sometimes eating your tasty treat.

I was very lonely last night, and somewhat hungry, so i grabbed me a loaf of bread and made myself one hell of a Fluppernutter.

Frupple 

When a boy and girl are more than friends but less than a couple. This typically occurs in a camp setting when two individuals hang out with each other quite often. Occasionally, but not necessarily this may eventually take the form of a couple.

"Have you noticed that Danny and Chana are always hanging out by the office bench?"
"Yeah they are definitely the newest frupple in ennismore"

Fluppet 

A small furry creature, with floppy ears and a small nose. Very fluffy and moves much like a Jim Henson muppet would. The Fluppet is a soppy animal with no predators.

David Attenborough: "Here, in the deepest, darkest jungles of Fluptonia, we see a family of three Fluppets, snuggled together in their nest, waiting for warmer weather."
