Being different results in you being a minority and alerts the majority to the fact that you are not like them
You could be taller or shorter than most, fatter or thinner, hairier or smoother, or uncut when most guys are cut or have a big cock relative to others.
Teasing whether in fun or with malice is based on a recognition of this difference. Teasing is most rewarding for those who do it when it gets a defensive reaction and ultimately the person being teased is the one who determines how effective it is.
Being different and being teased for it isnt bad unless you see the difference as being a defect.
So to your case in point.
Having a big cock (minority) in a group of small cocks (majority) makes you different and you are likely to be teased for many reasons, not the least being envy.
If the dude with the big cock reacts by going on the defensive like he has a major flaw and starts covering up and getting all embarrassed then the teasing frenzy is on. It is up to 'big cock' to use his other head and say wait a minute here what is wrong with this picture and react on the offensive, like it is an asset and the teasing is really a compliment.
If there were mostly hung guys in the dorm 'little dick' would be the brunt of the attacks. It's all numbers and reactions.
