A mix between Masturbation and Procrastination.
It is when a person masturbates to pass time or to evade someone, leaving their obligations to the last possible moment to complete/endure.
House Party Scenario-
Jamie: What is Jimmy doing? He has been in the toilet for 30 minutes now.
Kieran: Oh he is masturcrating in there because he doesn't want to talk to Judy, he gave her herpes last week.
Jamie: Oh damn! Well Jimmy... Masturcrate the night away!
