Amber Heard
To accidentally drop ones bowels in your partners bed, either maliciously, as a consequence of a massive intake of scrumpy cider or due to a swift exit from the rear entrance.
“Dude, I was going full bore on her back door last night, made my exit and she pulled an Amber Heard right there on my Eqyptian cotton”

“I had way too much cider last night, woke up this morning and I’d Amber Hearded my own bed, gonna have to get some new sheets, that’s way beyond the Daz door step challenge”
