Brand-washed

A person who is illogically devoted to a brand. Someone who refuses to wear, use, or purchase brands not within their previous allegiance to their chosen brands. These consumers will obtain products from their favorite brands regardless of their inferiority, expense, or aesthetic shortcomings.

1) Joseph spent $600 on that fugly Gucci fanny pack because he is so brand-washed to them.

2) I'm pretty sure Allison has joined the cult of Supreme. I wish I had created a company that pasted a red label on basic hats and t-shirts! I'd be rolling in the dough.

3) Her son literally acted bummed out because the new smart phone he got for his birthday wasn't and Iphone. He's been brand-washed!
