A guy who pretends to be your girlfriends guy friend but he is just waiting for a chance to steel her. He will cause arguments between you two and then say you are a jerk for being mad about her having friends....then the scumbag will always be there listening to her complain about you. And when you both break up he moves in on your girl.
Yo she said they were just friends now they are going out...That sucks bro that guys a Jackal

Excessive talking, sometimes to the point where it gets boring and drags on for way too long, aka rambling.
It's a slang word used by the company Team Volven.
"Bro the CEO talks so much I had to make a definition for rambling with his name in it, he's always jackaling about nonsense that has nothing to do with the previous topic."
