Aidan O'Brien

Someone who jerks off 8 times a day, and has a huge head.

Look at that Aidan O'Brien

Mr. O'Brien Science Brainrot

The Mr. O'Brien Science Brainrot is a subculture, religion, manuscript, and "disease", based on the life of Russell O'Brien. Due to his high-pitched voice, a voice recorded file of a Mr. Hanky soundin ahh fella went viral within New Zealand, bringing the group into popularity.

"William and Arman's conversion to the Mr. O'Brien Science Brainrot group changed my perspective."
"The legend of O'Brien's breakout of an ISIS facility through rat atom manipulation inspired me to convert to the Mr. O'Brien Science Brainrot"

Daisy O'brien

Daisy is the best person you will ever meet. She's probably a bit goofy and doesent really know how to spell but you'll love her anyway. She has the best taste in music and fashion sense and she's the prettiest person ever. She's going through a lot but she never talks about it and tries helping others instead. She's really funny to talk to and she's such a nice person that I would be surprised if somebody didn't like her. She will try match your energy as much as she can and she will never fail to make you smile or laugh. She can brighten your day just by being in the same room. She has the prettiest eyes ever that reminds you of a forest in day time. She's insecure but ignores it and tries to make you feel better about yourself instead.

If you ever meet daisy o'brien, take care of her and be nicer because I failed to do that
