Me and my highschool friend circle had this unique greeting style back in high school - we greet each other with insults in the format of "Hi/Hello, [insult]!", and do fistbumps. We always got weird stares for doing it, but we stood out for that. Until now, we still do it, but in moderation - I guess maturity takes a lot out of juvenile habits.
We got into trouble twice over that with the teachers (most notably with my "gayfucker" statement), so we subsequently did our greetings out of teachers' earshots.
I always look at myself in the mirror every single morning before going to work, all I see is an normal-looking guy. I don't stand out that much, visually. The only thing I maintain is my normal weight, weekend workouts even it out.
The only problem I have with my appearance is my hair. It's kind of mussed-up, no amount of hair wax or gel can make it better. It's like slightly curly on the front sides, and straight hair on the back. Dad says I inherited it from his old man, from which I start to curse heredity a bit. When I once let it grow out for 6 months my dad compared me to that guy on the movie poster of Eraserhead.
