Treacle

Harry and Ron really enjoy treacle tart, as does Dr. Dolittle. (read the Harry Potter series and The Voyages of Dr. Dolittle)

Triskaidekaphobia

Have no fear! 13 is my "lucky" number.

Banshee & Presage

A banshee is a presage of death.

Phlegmatic

I can think of a few people this might describe, but not many.

Quotidian

I could use this word every day, it's so cool!

Funnist

No, it isn't a word. It should be "funnest", which also is not a word.

Potable

The water in the Gulf of Mexico (in which I swam today) is not.
