Extremely cheap generic or store-brand instant Japanese noodles (usually sold for $0.50 or less per package) of inferior or questionable quality and/or flavor. Derived from the professional wrestling term "jobber" (a performer who is perpetually assigned to lose; a performer lacking in the skills or charisma needed to become a top talent, often relegated to wrestling in opening matches at the beginning of shows) and the Japanese word "ramen" (an adaptation of a Chinese phrase that means "pulled/stretched noodles").
After I was laid off during the dot-com crash, I lived on jobber ramen for six whole months.
What? You're eating Sapporo Ichiban? Lucky bastard...all I can afford right now is jobber ramen.
