🎈 Funny Birthday Wishes for Little Brother

Happy Birthday, You Little Trouble Maker! 🎉😂
Happy Birthday, little bro! You’re growing up so fast—I mean, not in height, but in age at least. 😆 I still remember when you were tiny, annoying, and smelled like baby powder. Oh wait, nothing has changed! Have a fantastic day filled with cake, presents, and hopefully, a bit more maturity (but I won’t hold my breath). 🎂🎁

Another Year, Another Level of Annoying! 😜
Happy Birthday, little bro! 🎉 It’s amazing how you keep getting older but never wiser. I thought by now you’d stop stealing my stuff and bothering me every second, but I guess miracles don’t happen. Anyway, enjoy your cake and presents while you can—I might just “borrow” one of them later. 🎁😏

Happy Birthday to My Built-in Prank Victim! 🎂🤣
Happy Birthday, bro! You’ve been my favorite experiment subject for all my pranks, and I appreciate your patience (or lack of choice 😂). May your day be as awesome as the time I convinced you that you were adopted! Just kidding… or am I? Have a great one! 🎈🎁

The Coolest (and Only) Brother I Have! 🕶️
Happy Birthday to my little brother—the only person who can go from cute to annoying in 2.5 seconds. 🎂 I hope your day is filled with joy, gifts, and maybe a little break from annoying me (wishful thinking, I know). Enjoy your day, troublemaker! 🎉

Congrats on Another Year of Being a Menace! 😜
Bro, you’ve successfully survived another year of getting on my nerves. Congrats! 🎉 Now, let’s celebrate with cake, gifts, and maybe some sibling wrestling. I promise I’ll go easy on you this time… maybe. Enjoy your day, little gremlin! 🎂🎁

You’re Officially Older… But Not Wiser! 🤣
Happy Birthday, little bro! Every year, I wait for you to finally act your age, but here we are again. 😆 Keep being your goofy self, and I’ll keep pretending to be the mature sibling. Hope you have an amazing day (and save me some cake)! 🎂🎈

Happy Birthday, My Favorite Pain in the Neck! 😂
Happy Birthday, little bro! You’re like a mosquito—annoying, always buzzing around, but life would feel weird without you. I hope your day is filled with laughter, gifts, and a moment of silence where you’re NOT talking. Just kidding! (…or am I?) Enjoy your day! 🎉

Another Year of Me Tolerating You 🎂🤣

A Year Older, Still No Superpowers? 😆
Bro, I remember when you thought turning older would give you superpowers. Yet here we are, and you still can’t fly or read minds. 😂 Happy Birthday anyway! Maybe this year, you’ll develop the ability to clean your room without being asked! 🎂

Happy Birthday, My Favorite Personal Assistant! 😜
Little bro, I just want to thank you for another year of fetching snacks, being my scapegoat, and doing all the things I didn’t want to do. 😂 Have an amazing birthday—your reward is… being my brother for another year! Lucky you! 🎉
