Three-Minute LumberJack

When you "jack" your "wood" (ie. masturbate) with the goal of achieving orgasm within 3 or so minutes due to a time limit.

I had to master the Three-Minute LumberJack while in the gulag because of the 3-minute shower time limit.

I woke up late with morning wood, so did a Three-Minute LumberJack and ran to work. I had a really great day.
