The absolute whole amount of something, maximum
quantity or
intensity, such as turning a
tap on full, it is all go, all happening and 'full on'.
Rents: " How is University?"
You: " It is full on, I have 2 assignments due tomorrow and a 4 hour lab this evening, exams next week, a cold coming on, no money, no food in the house and everything is just FULL ON!"
(oh yes and I forgot to mention my
hot date later tonight~ I got the cold, and the
cold sore off them as well;)
