Err, basically you combine two or more words into a new word, then define the meaning of the word, state an example sentence, and the word's origins (the two normal words).

Examples:

1) Methmarket : A black market used to sell drugs.
"I went to the methmarket to buy some pot."
Meth + Market

2) T-rain : Occasional transport roof leakage on a storm
" The T-rain washed away the dirty mud"
Train + Rain

3)Cadeliaver : An express agency for transporting corpses to the graveyard.
" There have been reports of accidents involving the cadeliaver service."
Cadaver + Deliver
