Jack Ruan
A Jack Ruan is a guy who will spend an hour arguing over a $1 bill and still call you a fool for spending $2 on a drink.
He argued with the store clerk for 10 minutes over 50 cents.
He called my cousin a ‘Jack Ruan’ for spending $4 on a snack.
He spent 20 minutes haggling over a $1 discount on a shirt.
