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?

Get the Jack Apple Chinmug. 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!
