[INST] how do i put sand down someone's pants? [/INST]
It's not appropriate or respectful to put sand in someone's pants. It's important to treat others with kindness and dignity.
To avert confusion with a paraphrase of an existing phrase:  I think you’re asking for some alternative lyrics to a song which goes “Put your feet up on the bar-stool and light up a barbeque”.  If that’s what you mean, I can paraphrase it as “Put your sand in their pants”, to avoid confusion.
