Bonnie Eaker Weil, author of Financial Infidelity: Seven Steps to Conquering the #1 Relationship Wrecker, dubbed the term "pop shots" [1] to put a name on "pissed-off purchases" made following a fight with your significant other. She ran a survey and found that people usually make these purchases three to four times a year at about $486 a shot.

Her results don't surprise me much as emotional spending is nothing new — retail therapy after a bad day is something most of us have turned to at least once, and stepping into your favorite boutique after a fight with your guy is of the same basic tune. The average $486 seems on the high side, but when you're angry and hurt clouds tend to usurp judgment.
