What does it meant to you?

I was just thinking today about the meaning that we all individually connect with words. When i use some words i think of the particular meaning it holds to me and sometimes i venture so far as to think, "I wonder what connotations any one else attaches to this word."
Today i overheard my coach describe a boy on the 17-yrs team we were watching as barrel-chested. And to me, because of the connotations with the word barrel and the shape of the barrel, i think of a 'barrel -chested' person as having this huge curved chest that sticks out. Absurd sounding but you really need to see my mental picture.
Just a thought i leave that with you.
