Smallbone refers to a woman withdrawing consent mid coitus, resulting in the man’s penis shrinking slightly, but remaining erect - requiring him having to finish himself in shame.
Man 1. Mate, I’m not happy! Sharon gave me Smallbone last night because I told her avocados were overrated while we were getting jiggy!

Man 2. I feel ya buddy - Carol smallboned me last week when I forgot her cat’s name.
