When one has to calm down an erection or is in a social situation where one is not appropriate. It also means to use imagery that is unappealing or unattractive in order to calm one's raging boner down to a level of social acceptance.
"Dude I was at this wedding and I popped a boner and had to think of my grandma in a bukkake video to calm it down. Nice masterdebating skills."
"I masterdebated yesterday during a job interview. What did you think of? I thought of Danny Donaduce in a speedo eating a chocolate covered banana."
