ALT + Tab 

Alt + Tab is a combination to switch tabs on most PCs, making it an easy way to fool teachers and other people into thinking you're doing what you're supposed to be doing.

Person 1: Holy shit, moms coming!
Person 2: I better ALT + Tab to my homework before she catches me...

Alt+Tab Fever 

(n.) Condition where a game or application doesn't take kindly to Alt+Tabbing and always manages to fuck itself up somehow when you Alt+Tab. (This could mean graphical artifacting, glitching, freezing, or just plain refusing to open up again, among other prognoses).

Fallout 3 has Alt+Tab fever. Every time I tab in, the pots are on the fritz, my pip boy goes black, and the world promptly ceases to exist!

Skyrim has a minor case of Alt+Tab fever, because you have to tab in twice to get it started again.

Any game released before 1999 can be safely assumed to have Alt+Tab Fever. Good luck tabbing back into that.
