An all around asshole (a jackass if you will). He plays girls without giving thought to the fact that it’s hurting them. A Jack will only do what is beneficial for him and will take down others in the process.

Someone you will meet and instantly connect with. One of the smartest, sweetest, and funniest guys you'll ever meet. His smile will brighten even the worst days and he will never fail to make you smile. He always rejects compliments and refuses to acknowledge that he is a cutie and is the best person anyone could ever come across. He is extremely intelligent, impressing everyone with his intellect. His sense of humor is extremely sarcastic, which will leave almost anyone gasping for air, due to his hilarious jokes. Overall, anyone would be lucky to meet a Jack, and even luckier to befriend one :)
