What is off my penis?

Suggesting that One is intruding in another person's personal affairs. More like "mind your own business"

"Hey man, are you still banging those 3 girls"
"man stfu, and get off my penis"

Also,
When a person is being extremely bothersome in trying too hard to impress a person

"did you like how I painted your house,washed your car, and cut your grass?"
"You are ALL UP ON my penis"...calm down
