The English language might have a word for someone who revels in ignorance about what psychiatric experts have called a very real psychological condition for decades, but I'm pretty sure "cynic" is not it.I'd actually argue that calling an anorexic "string bean" is okay because anorexics are delusional morons who have lost grasp on reality due to their feeble minds being consumed by superficial bullshit. But then, I'm a cynic with very little patience for the stupidity of my fellow man.
To follow up on Guest Poster's remarks, the "friendliness" of a nickname is not determined by the giver, but by the receiver.
The way I see it, the giver of a name determines his own intent, but that's about all. Whenever you hear one of those stories on the news about kids who kill themselves after years of bullying, it usually turns out that 90% of their bullies weren't sociopaths who were actively seeking to destroy their victim, but dumb empathy-challenged kids who thought they were just having some friendly harmless fun right up to the end and were sincerely baffled their actions actually hurt someone. Their defense that they didn't mean any harm ultimately doesn't make a difference in practice.And "friendly" is a word denoting intent. The giver of a name determines the intent and therefore determines the friendliness.
In the end, both 'crispy' and 'bacon' are IMHO rather tasteless ways to address burn victims regardless of intent and as mentioned in my previous post, it's mostly the association that's being made that does it.
