To do other things while masturbating.

"When I was multitaskabating last night, not only did I get off, I also got to watch Tosh.0 and file my taxes."
"With multitaskabating, I can keep up with my other day to day things!"
Mom- "Son, what are you dong in there?"
Son- "Multitaskabating! Almost finished!"
Mom- "Okay! Hurry up, dinner is getting cold! Don't forget to wash up before you come down!"
Son- "Believe me Mom, I won't forget!"
