What is Mow Muffin?
1.
The dried-on caked-on grass from the underside of a lawnmower which falls off in muffin-like clumps when starting a mower which has been idle for a day or days. In extreme cases, the mow muffin must be chiseled loose.
The lawnmower scattered mow muffin all over the garage floor when it started.
