A little notebook, or pad that you put girls numbers in that you have accumulated.
After many nights at the bars writing numbers on bar napkins or recipts and loosing them. Ben finally bought a little note book (holadex) that fits in his back pocket, and carry's a pen with him. He put's girls numbers in it with side notes to remember which one is which. Ex. Sarah - Big ass tits, Jamie - Tequila body shots... He officially has a Holodex.
