deal monkey
n.— «This cynical world has produced contrition up and down the Street, but no one is about to pull out of the hustle. Each investment bank employs what are affectionately known as “deal monkeys,” whose job it is to improve a bank’s standing.» —“Gaming the Game: How Street Plays the ‘League Tables’” by Dennis K.
