A significant other is someone who has good credit and is in a relationship with someone who has bad credit.
Significant
Sign if I can't
Significant
Sign if I can't
I want a new whatever but my credit score low so they say no to a loan.
Got me a significant other.
Looking all cute and shit, take significant other with me to get new whatever and apply for loan again. When they say no, I look at my significant other and bat my eyes and they will sign if I can't.
