Fill Up Your Tank 

To pregame or drink before you begin your night out on the town. To consume alcoholic drinks at one's home, perhaps due to: a rough economy with hard times, being an underage child without a fake ID, or in most cases, insurance for good times.

Me: "We're going to a speed dating event tonight???"
John: "Yep at 10pm"
Me: "Wanna come over and fill up your tank at 8?! I'm gonna need it!"

To drink heavily to the point of getting zonked out of your mind.

Last night I tanked up so much, that I passed out and dreamed that I was swimming in a sea of beer.
