rusty thumbone 

Similar to the rusty trombone, only performed when masturbating. You insert your own thumb into your rectum (left or right hand, your choice), bend your wanker down between your legs and crank your pecker between the four remaining fingers of the same hand and your palm. The beauty of this is that you have a free hand to eat a sandwich or work the TV remote.

Steve: "When I get Lisa good and tanked, she'll like my anus like there's no tomorrow, then she'll leave my house and go lick Tony's ass. She love's ass"

Ramone: "She's a whore, she didn't come over last night for her usual drunken booty-call so I had to give myself a rusty thumbone. I hear she was licking Matt's ass"
