When it comes to guys and drinks...the deal is, as always, very simple and clear cut:

Domestic Beer: He's poor and wants to get laid.
Imported Beer: He likes good beer and wants to get laid.
Wine: He is hoping that the wine will give him a sophisticated image to help him get laid.
Whiskey: He doesn't give a damn about anything but getting laid.
Tequila: He is thinking he has a chance with the toothless waitress.
