When a person has an irritatingly large number of coins stuffed in their wallet. Someone who is coinstipated needs to take a "coin dump" on their next purchase, in order to relieve pressure and reduce discomfort of the wallet and/or pocket regions.
"I keep paying in bills and now I'm so coinstipated that my wallet feels like it's about to explode!"
