A 'Doctor Jimmy' is the act of sexually assaulting/raping someone, usually a woman. The reference is taken from the the chorus of Dr Jimmy, a song by
The Who, where 'Doctor Jimmy' is an alternate, woman-raping personality of the main character in the rock
opera Quadrophenia.
"
Damn son, I heard
Keith's in jail!"
"Yeah, he was drunk and pulled a Doctor Jimmy on his
brother's girl, Heather."
