1. I plan on spending all my money before I kick the bucket. I’m not going to leave a penny of it to my relatives.
2. Your father hasn’t yet made a will. He doesn’t plan on kicking the bucket anytime soon.

The expression can be either disparaging or light-hearted when used about oneself or one’s relatives (opt.1&2), or disrespectful and impolite when used about someone else (opt.3).
