Griswald 

A small pressure-triggered grenade, about the size of an AA battery. Can be hidden in foods like bread or soft fruits, which is why you NEVER eat in hostile territory.

Neil foolishly bit into the apple the shady stranger gave him, and a small explosion blew off the bottom of his face. A griswald was hidden in the apple.

griswald knot 

A large and complicated knot. Taken from National Lampoon's Christmas Vacation when the main character, Clark Griswald, passed off a string of lights in a basketball sized knot to his son. It's most commonly seen made of electrical cords from game consoles and computer systems.

Good luck getting that out. It's wrapped itself into a Griswald Knot.

Griswald syndrome 

Fear or anger felt upon the realization that you neighbors have more holiday lights than you do.

Lori developed Griswald syndrome after seeing her neighbors Christmas lights. All she talks about is how she needs to get more lights up.

Lazy Griswald

When someone decorates for Christmas by buying lots of large tacky items and then scattering them over their property to make it look like a ton of effort. Especially applicable to large numbers of inflatable decorations.
