do all men say the same thing on purpose? or is it nature?

so first off, im a guy, and one of the bs lines i used to use on girls back in high school was that i was talking to them because their voice was the last thing i wanted to hear before i went to sleep, usually while i was texting others, or had another to call after, i thought this was original and i was the only one to say that, then i heard it on t.v. years ago. as time went on, lines that i thought i had come up with all by myself you would hear guys saying or see in funny texts online, so, i guess my comment is, women-we really do think what we say is original, and guys, is there anything you thought you came up with and then later realized it was completely common, and any ideas why this happens? my answer-women wanna hear the same thing so we all come up with the same things. your answer
