Dutchian 

A person from the Nederlands who believes they know everything, including English, better than anyone else (including English speakers).

That guy is a real Dutchian, he thought he knew the definition of "school" better than I do!

Non-Flying Dutchman

The Iceman. DB10. Bruce Rioch's sole stroke of genius. The finest import in the history of the Premier League. An enigmatic, reserved, ice-cold magician with an inexplicable phobia of flying.

It can naturally also refer to any other person of Dutch descent who suffers from pteromechanophobia.

Martin - Who was that player who cruelly toyed with Nikos Dabizas before slotting home against those Geordies around 2002?

Nige - The non-flying Dutchman, of course.

Martin - Ah yes, how could I forget...Whatever happened to that poor lad Dabizas?

Nige - He was clearly traumatised by the Dutch master

The Laughing Dutchman

When you fart under the covers and pull the blankets over your partners head... then tickle them so they are forced to breathe deep in between bouts of laughter.... and tears.

Karen: Hey, smell this flower my boyfriend gave me!
Alyssa: I can't, Matt gave me the Laughing Dutchman last night and nothing has been right since...
Karen: Is that why you have been crying all day?
Alyssa: It was taco tuesday.

Dutchland 

Def 1: Archaic and true German-Based name of Germany, based on the German name (Deutschland).

Def 2: An incorrect name for the Netherlands.

Those who are easily tricked will fail to realize that the term "Dutchland" really refers to Germany, and not the Netherlands.
