Sell out

Someone called Sofi who advertises too much things to her Uppsala located fanbase, things that no one would ever buy if it wasn't a recommendation from their beloved Sofi.

Person 1:Wow I Love that dress from "a brand" that Sofi mentoined in her story.
Person 2: Nah I would never wear that, she just advertises things for money and fame, she's such a sell out.
