A cocky 7th grader-(6 more years until grad)-that thinks that getting into Boston Latin School is their biggest accomplishment in life-yet it’s the start. They usually have fat bags and will run to lunch while bulldozing you if you are not careful. Refusing to use their lockers, if you get hit by one of their bags, you WILL end up in the nurse. They also seem to use roller bags. New sixies get shorter and shorter each year and more and more brutal. Their locks also get flipped a lot
Sixie: I am best kiddo and I am cool
Upperclassman: Pushes him into locker and makes him cry

Sixie: Yeah, I'm in Cluster A!
Mascot: GO WOLFPACK!

A person six years away from highschool graduation. Normally these people have giant back packs because they refuse to use their lockers. They are always scrambling around the school and complain about legit EVERYTHING! They think they are "the cool" but really they just live in their own world where they can not see how average they are. Besides those things they are pretty normal, and nobody thinks they are as cool as they think they are. But that's okay, we were all them at some point.
"Goodness Gracious!!!!! That sixie just plowed right through us!!!!!!"

Someone who would be ranked a six on the fuckability scale, but is still somewhat sexy.

A combination of the word 'six' and 'sexy.'
When I woke up next to her she wasn't the ten she was last night, but she was still sixy.

Six men in Harry Potter, Daniel Radcliffe (Harry Potter), Rupert Grint (Ronald Weasley), Tom Felton (Draco Malfoy), James Phelps (Fred Weasley), Oliver Phelps (George Weasley), and Matthew Lewis (Neville Longbottom). The name "Sexy Sixy" was created by two girls at a sleepover so they could refer to the men easily.
Girl One: Who's your favorite, Daniel Radcliffe, Rupert Grint, Tom Felton, Jam--

Girl Two: Why don't we call them something else? Like... the Sexy Sixy?

Girl One: That's a great idea! So, who's your favorite Sexy Sixy?
