An amazing guy, makes any girl feel like the luckiest person ever - tall and strong can pick you up despite you not thinking he can. He knows how to make you laugh and has a lovely character - If you are not careful, you will spend hours on the phone to him or when you are with him you can see through his eyes - depite their awesome sexiness
If you are so lucky to meet a "jack" you will spend countless hours with him and find yourself with a most esteemed companion even though he can be cheeky sometimes......
may have a badboy past but thats ok because he is easily changed with his own mistakes
