Kafreen
A person who can't stop talking about themselves and thinks they're the best. They might buy you stuff, but only if it helps them feel better.
I bought you a soda to make you like me more. I'm the best. You're just a soda.
You're only my friend because I want to feel good. Don't get too cocky.
I bought you a snack so you'd like me. I'm amazing. You're just average.
