fiction lag 

The temporary change in personality that occurs after being deeply involved with a movie, book, game, or some other work of fiction.

Can also be expanded to nonfiction ("documentary lag" or some other variant), but is less common because those works are typically experienced through the frame of the reader/player/watcher's default personality.

CHRIS: Don't think. Don't hesitate. Just say it.

ASHLEY: Why are you talking like that?

CHRIS: What?

ASHLEY: You sound like a movie trailer. Is this because you just finished watching Fight Club?

CHRIS: Uhh... yeah I guess I'm a little fiction lagged.

Beer Lag 

The 2-3 hours that disappear while you're out enjoying yourself in a bar and then get added on the next morning at work between 9 and 11.

net lag 

A feeling like jetlag that happens after you use your computer after sunset and the bright backlight tricks your body into thinking it's still daytime.

(For details, google "photoentrainment".)

I was online until midnight last night, and now I feel like I'm still on Tokyo time. Net lag sucks.

Movie Lag 

Similar to jet lag; symptoms include disorientation, headaches, fatigue, confusion, nausea, sensitivity to light and possible constipation.

A condition one may experience after viewing a film. Especially if the film is particularly long or if you enter the theater during daylight and exit when it's dark outside.

(Two friends exiting theater)
Richard: Man, I really loved Magnolia, but it was quite long.

Austin: Yeah it was. We sat down at 4:30 and didn't get out until past 8:00!

Richard: Well, I've officially got movie lag...
