That is his nickname for his dildo.
He has this thing called the Autobutt 4000. He fills it with warm mayonnaise and prances around the house singing show tunes, which he punctuates by delivering full thrusts intermittently.
"Clang clang clang went the troLLEY!"
"O-klahoma where the wind comes sweepin down the YAAAARGH!"
He makes my life a living hell. But he's my son - or daughter, depending on what day it is. And when he's using the Autobutt 4000, he usually stays away from my panty drawer.
