Flutterbutter 

The overwhelming feeling of dread caused by dropping your piece of toast and seeing it fall on the floor buttered-side-down

*Avraxia drops toast* "Did it...? GODS NO!! IT FELL BUTTER-SIDE-DOWN!!!"
*Silver hears racket* "Avarxia, are you all flutterbutter again??"

flutterbutt 

The noise made by butt cheeks flapping together as gas is expelled violently. This usually occurs after consuming several bean burritos, drinking a warm coke and jumping on a trampoline.

George sure is noisy today. He has a terrible case of flutterbutt

flubberbucket 

It's basically a casual insult
If someone insults you and you want to get them back, but don't want to hurt their feelings too badly, just "flubberbucket" them ;)

BFF- You're stupid
Me- Well, you're a flubberbucket

Flubbergutted 

When you go down to eat a girl out, and instead of hitting her vagina you end up with a roll of blubber in your mouth similar to that of a humpback whale.

Boy 1: I was so drunk last night when I took her home that when I pulled my tongue out I didn't realize that I had flubbergutted her.
