A person who prevents everyone around them from discussing the finale of "Lost" because they haven't watched it yet. The prefix "Jack" comes from the first name of the candidate Jack Shephard. The suffix "off" refers to the person being a jerk-off.
Co-worker 1: Holy cow! Did you see "Lost" last night!
Co-worker 2: Shhhhh! This Jack-off dvr'd it last night and watched the ball game instead. We'll have to talk about it tomorrow.
Co-worker 1: What a jerk-off!
Co-worker 2: You mean Jack-off.
Co-worker 1: Yeah, whatever.

When Spider-Man rubs his wrist using his hand until a white sticky substance is released, often called, "His Webbing". Spidey often uses this "Webbing" as a form of transportation among other things in order to save the day. This is why when Spider-Man isn't horny, the day does not get saved.
Person - "Help, I'm being robbed!"
Spider-Man - "*Frantically rubs his wrist and moans* Come on you son of a bitch!"
Person - "Is he jacking off?"
Spider-Man - "*Frantically rubs his wrist and moans* Come on you son of a bitch!"
