Speed Charging 

When you realize you phone, iPod, laptop, electronic is about to die as you are going to leave and you uselessly believe if it sits on a charger for five minutes it may last a few hours. Even though it makes little difference

Person 1: dude we need to leave what are you doing?
Person 2: Speed charging my phone it might last a little longer
Person 1: it doesn't help... I'm leaving

Technique rumored to have originated at 320 N. Tallawanda in which the speed of the gentleman's pelvic thrusting changes from super duper fast to slow as molasses and everything in between, thereby enhancing the pleasure of his lady friend and delaying his dick sneeze.

Brian: What? Did you say your girlfriend had trouble getting off last night?
Dan: Yeah, until I invented changing speeds.
