wrinkly dollar 

A phrase used to define someone who has a hard time accepting and believing a truthful compliment.

Ryan: Hey you're a pretty good artist and mathematician! You're so OP!
Me: Stop complimenting me. It makes me feel like a vending machine trying to accept a wrinkly dollar and it's just really frustrating for everyone involved. ;-;
