The chic at a party, who you can always ask for a beer, knowing that she'll get it for you. After she gets you three or four beers throughout the night, you can pretty much guarantee that you're getting laid. A booze wench is usually a ditzy, slutty lightweight who acts drunk before she even is, and whose name always starts with a consonant, never a vowel.
Orin: "Hey man, did you get any at the party last night? I saw that chic fetching you beers all night"

Eric: "Yeah man, that Steffi is a total booze wench"
