German: person who is a part of or aspires to the pursuit of middle class conformist comfort - nice house with a picket fence and a large car parked out front (and a fat retirement account).
From a Medieval German name for a small weapon carried by middle-class townsfolk, adopted as a slur on the bourgoise by 19th century socialists.
"My parents are total Spiessers. So boring!"
From an old German bank commercial:
A hippy in a trailer park is making fun of his neighbors, who have just gotten a mortgage from the bank and will be moving into a proper house: "Spiessers!"
His five-year-old daughter: "I want to be a 'Spiesser' when I grow up..."
