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)
