I've heard those before XD

My favorite one: "If you held up eleven roses and looked in the mirror, you would see twelve of the most beautiful things in the world."

Or nerdy ones: "Are you a derivative function, cos' baby, I wanna be tangent to your curves."

"Your torque looks good from this angle."

"Baby, you must be a current, cos' you're irreistable!"

Or um, "Nice shoes" always works
