What Is A Pome?

 
For those who incorrectly guessed  
A pome is a brief quest  
Lasting nowhere near as long as a tome  
Unexpectedly ending shortly after it starts  
And in the privacy of your own home  
May involve K-Y Jelly  
A lawn gnome  
Perhaps auto parts  
Sometimes it feels really good  
Mostly it smarts  
So, don't be a hero  
Like when in Rome  
I suggest you do as the Romans do  
Except for Nero  
Best known for accidentally burning everything down  
While lighting his own farts
