Fenfen 

A woman who upholds a high standards of everything that she does - charismatic, charming, gorgeous, elegant and intelligent. A true perfectionist that knows no bound when it comes to accomplishing her dreams and desire.

Fenfen is such an inspirational, exemplary figure that I'd love to be when I'm older.

fefendeferous

1. The sinking feeling that your work week has begun, but it is actually almost over.

2. When you hate your job so much that you feel like every day is Monday.

Even though it's Friday, the porn theater splooge mopper often feels fefendeferous.

Fenbendazole 

Fenbendazole is a dog dewormer which can reduce and possibly cure cancer. It's unclear whether it works for all cancers but some studies suggest it shrinks tumor size. It could be a good alone or as an add on treatment to surgery and chemo.

Tyler: I took 222mg fenbendazole and also got surgery and chemo and cured myself of lung cancer. I took more fenbendazole just to be on the safe side and ate fruits and vegetables. Now I don't need fenbendazole anymore.
