Dumbfuckalitis 

Dumbfuckalitis is a severe disease commonly affecting millions of people in their workplaces across the world. The disease causes them to become dumbfucks (see definition). A bad case of dumbfuckalitis also causes laziness in said dumbfuck.

It is also known for dumbfuckalitis to affect people outside of the workplace.

Seems to be very prevalent in Great Britain.

Boss, "My HR manager hired a dumbfuck who has now spread dumbfuckalitis in my company and now I have to lay them all off. FFS!"

dumbfuckary 

When one acts solely on what they believe to be true but are too stupid to verify their sources. Usually an ongoing chain of events started by one dumb ass action or comment.

Normally I'm the first to accuse Tiscali of dumbfuckary, but in this case BT really has behaved scandalously.
