I was just walking back from class and there was a group of people from my computer science class.
As a passed a straddler I heard him say 'Oh shit, I'm lagging.' Then he ran up to the rest of the group.
I know that this is a propper use of the word 'lagging', and the computer term 'lag' comes from this but the guy definatly meant it in the computer term way.
