A cheap, fortified wine that is immortalized in the following sequence:

person the first: " What's the word?"
person the 2nd : "Thunderbird."
person the first : "What's the price?"
person the 2nd : "Forty twice."
person the first : "How d'you drink it?"
person the 2nd : "In a cup."
person the first : "How's it get you?"
person the 2nd : "Fucked up."

Thanks to spacewrench for the last 4 lines, which I'd never heard before.
