1.
Derived from the saying "I'll see you in a bit" but obviously shortened for easy use. Obviously this word means exactly the same as "Good Bye"

what you would say if you don't want to do something or feel awkward answering a question. It's also used to greatly annoy. There are many spin-offs of "inabit" like: "Scrinabit", "Guysdadabit","studyabit", "inamonth", "inayear" and "inawhile".

Inabit is a mixture of words strung together and is quite often used by chavs to intimidate or forcefully reject other people, if one chav says it to another, tempers often escalate and there is in most cases a fight over "Inabits". Its also a common threat to mean that the other person will see you later and bang you out. Basically its for people that think they are hard. But really are not, instead of shouting Inabit they would prefer to sit at home with their moms and watch soaps whilst knitting. Ok then. :S
"yeah Inabit mate!"

or most commonly just randomly shouted out loud.(In a deep rocky hard voice)

"Inabit!!"

It's never going to happen.
"Will you lend me twenty quid?"
"Oh yeah, in a bit!"
The phrase 'Never seen it" can also be used although as the phrase is only used in the North West of England, it should be pronounced 'Neva sin it'.
