witlag

Someone who is slow on the uptake. This person often laughs a long time after a joke's punchline.

He laughed at that joke so late that he obviously has witlag.

In the Star Trek movie, Generations, where data finally got the joke from the episode, Encounter at Farpoint.

"Data, I made that joke seven years ago" - Geordi
"I know, I just got it!" - Data
