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.

Monomania

Not me, not so much.
