I love how this word is so dramatic! Instead of saying huge or enormous when you say something is Brobdingnagian, it always gets people's attention - mostly out of curiosity to know what the heck that is! I love words with a back story.. in this case being Jonathan Swift's Gulliver's travels. Yes there are a lot other words I love as well - for similar or different reasons - but this one came to mind first. Some others I love are effervescent, lackadaisical, scrumptious, wanderlust, blasphemy
It's not just this word, but every word associated with it. People who go about uttering obscenities or profanities and think they're cool if they do that - are the lowest forms of life in my opinion. I especially am appalled by those cuss words that essentially degrade human relationships. Respect, please.
