(word ending in "er) her, i hardly know her

Another way to add sex to innocent things without saying "that's what she said."

in (word ending in "er) her, i hardly know her, "Her" is the same person as "She" in that's what she said. It's a hypothetical girl that you have sex with.

When someone says a word ending in "er" you turn it into a sex joke.

So if a friend says, "Dude, I broke your windsheild wiper."
You say, "Wipe her? I hardly know her!"
