first date syndrome
A condition which involves the ability to have a great first date, but never experience a second for some reason. The first dates often come in a string together. Can be caused by bad breakups, commitment issues, or bad end-of-date kissing skills. Not to be confused with playing the field, which implies not having a second date by choice.
