I was always bigger than any of my classmates, boy scout friends, etc., but no one ever made fun of me except one guy. He was a high school senior and I was a freshman and we were messing around. He was obviously perturbed that I was quite a bit larger than he, so his comment was, "Well at least when I fuck a girl I won't kill her!" Apparently, that has stayed with me all these years...but I guess the last laugh is on him, because I ain't fucking girls!
Otherwise, all the guys that I grew up with never said much. Mostly just stared and most likely talked behind my back. If they had nicknames for me I never knew it.
But I have had problems with having a large dick. I'll never forget losing my virginity to a man. I thought I was being especially gentle and considerate but all the same, he bled and I felt awful...
