rewank
When you try to wank to something hot but something unsexy like meatspin or Rosie O'Donnell pops up or somebody walks in on you, and it goes limp but you're not satisfied so you have to wank all over again.
Dude I was jerkin it, but I realized I had Calculus homework... I had to rewank when I finished.
Rewank
When you are wanking or banging and your dick goes limp then you do somthing to make it big again.
I was wanking in the shower but it went limp from the cold so i needed to rewank once i turned the heat up.
