remove the word [retarded] from my vocabulary

My bosses at the camp I’m a counselor at have made a rule that we can’t say “retarded” so I’m going to have to meet this goal!!!

Well, I didn’t say “retarded” at all, but then everyone at school said it, so it kinda slipped into my vocabulary. But now our school has a major ban on it, and I can totally see how offensive it can be. I’m going to try replacing it with “ridiculous” (excellent substitute) and see how it goes!
