Her nickname is Untouchable because nobody can hit her in a fight. Also, I think most of her interactions with people can be explained as her being a tad awkward, her being a celebrity and people being intimidated by her probably made sure Pyrrha never had many friends, or her only friends were people like her trainers (who I assume were mostly male); either way it means her social skills leave a lot to be desired. Her acting "like a bro" to Jaune is probably because she's trying to fit in and not seem so intimidating; basically she's giving off the vibe of "She, I'm normal like you; don't be afraid of me!", but instead as coming off as non-threatening she comes off as boyish/jockish.
