The state of one's face the morning after a rip-roaring night of partying and falling asleep with a full face of make-up, resulting in a drastic case of raccoon eye or liquid liner leakage. This is a usual happening on Jersey Shore; most recently in an episode where we found Sammi the Sweetheart painstakingly picking mascara goop out of the inner corner of her eye after a rough night at the bar with Ronnie. Wash your faces ladies!
Sammi looked like crap the next morning because she didn't wash her face - mascara goop in her eye and liquid liner all over her pillow. She was suffering a serious case of make-up hangover.
The driver who chooses to stay in their lane with no signal, or intention of getting over, even though they have had ampel warning the lane is ending and they need to merge. "Lane lagger" can also be applied to the inconsiderate driver who knowingly gets into the lane that's ending during heavy traffic, because they'll get ahead a few cars since another driver will have to let them in.
Although anyone can be guilty of lane lagging, it's most often observed happening to drivers of high-end cars because sense-of-entitlement usually comes with the purchase of their vehicle.
"That lane lagger wants in front of me but doesn't have the courtesy to signal!"
"Officer, the BMW was lane lagging and merged right into my bumper at the last second!"
