The use of "jaaack" implies that someone disagrees or is against a certain remark or written response. "Jaaack" can be replaced for the word 'fuuuck' when the term is used properly. "Jaaack" can have as many "a's" as you desire, as long as it has more than 2.
"Bro, I heard you stuck it in Rachael's stink mink the other night" Jaaack that mate, would never go there!
