Asteroid 16157, Toastmasters, was discovered on January 5, 2000 by Charles W. Juels at Fountain Hills, Arizona. It has a period of 4 years, 129 days.
It was named for the organization Toastmasters International, which provides practice and training in public speaking and presiding over meetings.
The meaning of asteroid Toastmasters seems to be public speaking, shyness, learning to overcome shyness or stage fright.
The glyph for Toastmasters is mine and is based on the Toastmasters International logo.
