The time in the morning that's in between grabbing your cup of joe, and the caffeine kicking in. Usually spotted in drivers who don't seem to be "all there" during the morning rush. As if they grabbed their coffee when leaving the house and hopped into the car immediately, instead of waiting for the effect before driving.
On my way to work this morning, I must've passed ten people suffering from coffee lag, I don't know if they even saw me.
