Lipogram

 Lipogram

from leipein , to leave out, and gramma , a letter—is a riddle in which a name or sentence is written without its vowels, as:
Thprffthpddngsthtng,
The proof of the pudding is in the eating.

Whnhnorslst ts—rlftd,

"When honour's lost 'tis a relief to die,
Death's but a sure retreat from infamy."
This riddle sometimes appears as a proverb.
"Fear's the white feather all cowards wear."
