You must be one of the many ladies I've had coital relations with, because that's the sort of thing those ladies say. (The men are more verbose but that's because I do butts good.)
Here are some other things I've heard:
"You really cleaned out the corners."
"Way to investigate the cave-mouth."
"Thanks for airing out the old box."
"I appreciate how you tided up after yourself."
"Nice hand jive."
"How many people were inside me?"
"That was efficient."
"It's like I got asked to the prom by a werewolf."
"Natural lubricant is for suckers."
"I feel like the paperboy just collected."
"The cellar door was ajar."
"That was a lot of chucks, woodchuck."
"In Soviet Russia, backdoor is left open for you."
"I can't believe you ate the whole thing!"
"That felt slippier."
Short Answer: Some of these are real. I'm not kidding. Good luck figuring out which ones.
Bonus True or False: Three days ago, someone in my bed said the phrase, "Work 'em like their not yours."
