look up any word, like dirty sanchez:
 
1.
An extremely attractive male, VERY funny, fun to be around with, sporty, pretty chill, a great friend, and is usually the boss in his posse. A Jadyn is AMAZING in bed and has a 11'' cock. He can win the heart of any chick wants even if hes not into them. Jadyn's love to troll around with their friends the occasional prank comes around. Besides that, a Jadyn is probably the coolest person IN THE WORLD, Totally equal with Chuck Norris, Bruce Lee, and flaming Ninja's. If you dont know one; your defiantly missing out.
Oh man, Jadyn is sooo awesome! I LOVE HIM!

A girls name formed by combining the name Jade: a precious ornamental rock that stands for wisdom, beauty, and grace, and the name Jayson: greek for the goddess of healing.

All girls named Jadyn are rock stars who are extremely likeable and easy going.

Alternate spellings: jaden, jayden, jadon, jadin
I wish I was a Jadyn...
There's only one Jadyn and you're not her!
That girl Jadyn is dope!
