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!

Every video his viewers go on "A jaackmaate journey" as he discusses the topic of his choice. The 19 year old boy is extremely honest and is truly fucking hilarious.

Person1: Did you see Jaack Maates new video?
Person2: Yeah, he's a fucking legend.
