A phrase traditionally used by drunken yobs to rouse and rally the troops into a frenzy and to encourage evenings of dance,
music, intellectual discussion and hopefully later, some sex. However, the phrase can mean what you want it to mean. It's a metaphor on life, man. According to legend the phrase was first heard echoing around the streets of
Malia, an island in
Greece, only a year ago. Get the pump on.
