Students at Northwestern's Medill School of Journalism. Used in a perjorative sense by professors and outsiders. The word is formed by combining the school's name with a common pleasure instrument known as a dildo.
"I told you Medill-dos to get at least two sources for each story -- not just one. You say you want to be journalists but you are all too lazy," said one irate Medill professor.
"They're only Medill-dos," whispered the city councilman to his assistant. "They want to be journalists some day, but nobody ever sees any of their stories. You don't have to worry about what you say to them.
"That's why there's a pimple-faced kid holding the microphone. Nobody would put him on the air in the real world."
