18th Birthday Wishes

18th birthday wishes can be funny or serious — or both. But they should never be clichéd in any way. The average 18 year old has seen and heard it all (or thinks he or she has), so "corny" is out of the question.

The best 18th birthday messages tap into the mindset of your average 18 year old, who is consumed with social media and everything else online. In other words, you need original 18th birthday greetings that can penetrate this cyberspace-jaded crowd. You need to be "real" (not contrived or patronizing) with your birthday wish.

The 18th birthday messages on this page are 100% original and 100% real. Guaranteed! See for yourself.

Your 18th birthday is a special occasion — it's when you get to celebrate your leap into adulthood. You know what that means, right? Let's party until we puke! Happy 18th birthday!

Happy 18th! You finally know what it feels like to be "legal." It's just like before, except you can now buy beer with an ID that actually has your photo on it.

The word "teen" may be attached to the end of your age but that doesn't mean you're still a teenager. At 18, you're a grownup. It’s time to take on grownup things. Besides, you're more than ready. Happy birthday!

Happy 18th birthday! You must now act like an adult: You should not start voting (even though you can now legally vote) and should begin drinking (even if you can't drink legally until you're 21).
