I was one of the ones considered "creepy" because I was trans and still in pretty full transition at that time... Between the jack ass jock guys and wannabe jocks and wannabe bad boys, along with dismissive if not outright homophobic and transphobic teachers. I decided that that shit stain of a school wasn't for me. All the wealthier kids went there due to a general lack of private schools in the area, along with the fact that "wealthy" in that area was middle class, or people living on real-estate money from rental properties in California. The vast majority of the students were thusly entitled, conceited, douche bags.
But of the ones I did encounter before I opted for a more direct route to getting past high school BS....
Well there was a guy, call him Eric, he was gay, flaming femme gay stereotype walking, who only hung out with the "popular" pretty/cheerleader clique of girls. That's not what made him creepy. What made him creepy was for one, he insisted that I was gay and should go have sex with him in one of the more remote boy's bathrooms, on a regular basis, plus wouldn't take no for an answer. At least not until one of the cool and nice jocks threatened to break his neck if he kept bothering me. The other creepy thing is that he was caught by a lot of guys in the boy's bathroom peeking through the gaps in bathroom stalls.
There was another, let's call him Leopold, who was on track for class clown, except... Well he was a goofball, but he was also a real oddball and his humor leaned... Really sexually inappropriate, but only with the guys. He was straight as far as well knew, had a girl friend he was really into and really happy with. Still he'd do things like dry hump the other guys in my circle of friends and whisper things in people's ears "if we went camping together and you found a cum filled condom in your ass in the morning... Would you tell anyone?"
There was a girl, let's call her Samantha, she was a super tom boy, who couldn't get along with the girls. The only thing that made her stand out in terms of creepy, is aside from me, she was the only girl everyone assumed could kick any of the guy's asses. Unlike me, she was very confrontational about it.
Then finally there was a guy, we'll call Brian, who had a weird thing with forming homo-romantic attachments with any guy he tried to befriend. Not to mention that being his friend was a precarious place to be at any rate, he had few friends for a reason, he'd suddenly turn on someone and make them his personal mortal enemy for the littlest things. If one of his friends started hanging with someone he decided to hate, he'd burn bridges with that friend.
Basically all of those people were in my group, or class through out middle school and into high school. The majority of my friends were the social outcasts, though I did maintain some friends in the more popular sets, those where the cool/nice ones. Most of both schools though were filled with yuppie transplants from California, especially Southern California, who just had to talk shit about anyone who wasn't them constantly. In my mind, the ones I mentioned, not so bad, the yuppies were the real creeps.
