buyer's remorse 

when one buys an item and feels regret about the purchase soon thereafter. while buyer's remorse is normally restricted to expensive purchases that have probably busted the buyer's budget, this sentiment can also occur when a person buys a totally useless and inappropriate item.

This is not to be confused with winner's curse.

Karl: Chris has a serious case of buyer's remorse coming up pretty soon.

Ryan: Really? What makes you say that?

Karl: He just bought a silly ass Dontrelle Marlins jersey just bc it costs $30. Wait until he realizes that instead of buying something that will only make him look stupid if he ever actually wears it, he could have just saved; that dude loves saving money.

buyer's remorse 

The phenomenon of girls with low self-esteem who jump into bed with men (or women) they barely know, then afterwards are so filled by regret and disappointment and loneliness that they in some way try to justify their behavior by claiming that they were taken advantage of and didn't make a conscious personal choice.

"Well why did you sleep with him/her if it makes you this upset? Didn't you want to?"
"I...I don't know if I wanted to...I feel like I was taken advantage of."
"That's buyer's remorse bitch."
