Jack is typically a boys name. Jack is usually blonde and uses quite a bit of slang in his talk. He makes jokes all the time and if you play your cards right you could end up hanging with him or fucking him. He has an absolutely huge cock and loves to brag about it. He may be a bit short but is super tough and very strong.

Alicia: “He must be called Jack if he fucked you so good.”
Hayley: “ omg truuuue!!”
