Had a big night on the raspberry cordials. To your dismay you wake up the next morning feeling pretty good but for every hour your awake you feel considerably worse, until you eventually feel as hungover as you should if not worse.
Mate: I woke up this morning feeling fine considering how drunk I was last night, but I went to get some food and it just hit me like a bus.
Me: Haha, you did grab the bouncer on the butt on the way out of the club!
Mate : I think I've got a reverse hangover.

bonging a beer,
going to WAWA,
and getting slapped by a girl,
but nothing else

When you wake up and are hit with the remembrance of last night's out of control shopping escapade.
There are a few infomercials on during the day but at night they are featured on nearly every channel. Big Business knows that as consumers, our guard is down at night, so they capitalize by only feeding us shopping options.
"Shopping hangover" applies to infomercials as well as online shopping - since after around 11 p.m. people start to feel the need to buy everything they've ever thought about...and some things they haven't.
