When you want someone to leave you alone, get out of your way, get out of your sight ETC, you say: "Get off my pitch!"
Boss: "This is the 15th time you've been late for work!"
Employee: "Sorry Sir! My dog had a really bad seizure and I had to rush him to the vet."
Boss: "I've had enough of your stupid excuses. You're fired! Now get off my pitch!!!"
