The result of an intense night of binge drinking. One wakes with a sustained level of intoxication and proceeds to continue the drinking of alcoholic beverages. The intoxication is never lost, and hence, carries over. This is the opposite of a hang over.
"Forget having a hang over, I'm a trooper. It's time to CARRY OVER, give me a beer."
Basically, it is the effect of ya'll gettin drunk right quick the next day after getting crunk the night before.
After drinking all that Tanq on Friday, the carry-over had me buzzin after my first Belvi with no ice. With some conversation and Hennessey, my drunk ass had that tipdrill back at my place in a minute.
