Jack is a very kind person, and will try to protect you in he’s own way, which makes you fall for him, but he will break your heart.
Yeah Jack was my first love,

Not to be confused with the whiskey of the same name, this is a special alternative term to describe dimpled chins instead of "Butt Chin". Unlike "Butt Chin", this new term describes how the cleft chin itself is more shaped like an apple instead of the human buttocks, as with how the verticle cleft within the chin also resembles a vertical cut within an apple just like a Jack O' Lantern. "Jack" in this saying is meant to reference how apples are often actually used as Jack O' Lanterns sometimes instead of pumpkins.
Look dude, instead of making fun of my cleft chin and saying how much it looks like a butt, how about you just call it a "Jack Apple Chin" instead?

Jack is a boy who comes from a lineage of island cowboys, and although he is not one himself, he can definitely make you hee haw your pants off all the way to hornet jail. Feeling down? The King of Puns, Jack, will never fail to make you laugh and brighten your day. Although he has a questionable model of mammalian and reptilian classification, Jack is super tech smart and beats Geek Squad any day of the week. Stranded somewhere unknown? Jack is an expert at both rating “tropicality” and identifying unique and exotic birds, so he will determine your exact location anywhere on the globe. Not to mention, he gives the best advice for any problem you may have. Still have questions about his character? Jack is a family man, awesome with kids, and stray animals love him. I know, it sounds too good to be true but it is. Everything about Jack is wonderful, but the cherry on top is his super sexy voice—It cures insomnia. If you are not lucky enough to live in the same time zone as Jack, he will sing you to sleep on the phone. He has a habit of reading out loud complete paragraphs but this is a plus since you get to hear his voice more. You’ll have the best long convos with Jack. Jack is a really great bestboy friend to have (:

The act of performing 69 but with a Fleshlight on his pole. This athletic act is performed on the bed standing up and slowly jumping at a quickening pace. Near climax the Fleshlight is quickly disposed of and his donger is deepthroated and his love juice is deposited down her throat. Optional feature for experience Forum members. Timing a double climax is the ultimate finishing to this event. This is when both participants time their orgasm and she delivers a nice spray spritzer on his face.
When me and misses where in Waikiki, we stayed on the beach and banged all weekend long. On the final night I introduced the Jumpin Jack Fleshlight Forum and we both exploded. It was sooo hot!
