Noah has his tweeny friend over this afternoon, and they were getting packed up for Noah's baseball game tonight. I spotted his jock strap on the kitchen table and said, "Noah, please get that sick thing off the table." Noah and his buddy looked a little confused. Then I remembered that the word "sick" means the total opposite of what it used to mean. When they like something, they say, "Dude, that's sick!"
So I explained to them, "I mean 'sick' in the old-school way. Back in my day, that word meant 'disgusting' or 'ill'." They said "Oh! Ok then" and removed the objectionable item and went outside. I looked after them, feeling pretty old.
