fatlag 

The phenomenon of going on holiday for a week without gaining a gram in weight and getting on the scales a week after you get back to discover you've gained three kilos.

Got back from holiday last week unscathed, hadn't gained an ounce but got on the scales this morning to discover fatlag had well and truly kicked in.

failage 

When faith is so cruel that it pwns you with the amount of fail that it provides given the circumstances. In other words, a massive fail that marks you for the rest of your life. The ultimate self-embarrassment.

Example 1: Masturbating in front of your laptop when you've forgotten the webcam on after speaking to your grandparents in Florida would be failage.

Example 2: Letting the girl you have a crush on download a torrent using your PC without thinking of deleting or hiding the collection of BDSM porn first would be an even bigger failage.
