A user of 4chan's /a/ board, who, starting October 2010, started writing a story where he was inspired to brush his little sister's teeth after watching Nisemonogatari's infamous toothbrush scene. Eventually, it got to the point that they married and had a child together. He kept posting for about 3 years, until August 2013, when he was never heard from again. Nobody knows if the story is real, but nobody can prove that it's false either.
Aidan: "yo have you heard of that one Oral Hygiene Bro who fucked his sister"
Bob: "Yeah that's some messed up shit"
The Hot Girls at the Dentist Office who clean your teeth and tell you to brush more often. They accidentally brush their breasts against you and use the suction too.
A dental hygienist is the cuteblonde who cleans your teeth every 6 mos. that you secretely have a crush on.
A self sufficient person who is somewhat a masochist. Likes to stay up to study but complains about not getting enough sleep the next day. Has 2000+ photos of the sky because she would rather do that than actually study before midnight. Loves cats and everyone seems to depend on her for help on anything related to school. This is the one person in the class that actually listens to instructions. She will constantly tell you not to do things even though she sometimes does those things she told you not to do. Waking up early then just sleeping again is a daily occurrence for her. Still, very supportive and is liked by everyone.
