"You know in every clique there's a loner right?" *nods* "Well he's the one whose balls can't be touched. As in, you can't touch his balls."
Metaphorically it either means he's sensitive OR he's actually the big scary boss whom you can't make fun of.
Either way, I need to know where have I heard this line before in real life, cos I doubt my pretty little mind could've come out with such an intelligent insight by itself.
What a weird morning.
