Hand gravy 

When a person rubs his girlfriends pussy and uses the juices to jerk off.

Babe, I can I get some? Sure honey.....I'm not hard yet so let me get some of that hand gravy to jerk off with!

Second Hand Gravy 

Unbeknownst to you, your girl took a jizz blast while getting slammed in the ass by her side piece prior to coming home to have you rim out her chocolate starfish. Whilst eating her asshole, a/k/a tongue thumping her fart box, you unexpectedly taste something salty. You take a look at her "brown eye" and notice a creamy ooze beginning to flow from her bowels.

"You're not the first one at the buffet. So, how about some second hand gravy?"
"Last night my girl came home primed and ready to go. Little did I know breakfast was about to be served with some second hand gravy!"
"Could I get some second hand gravy with that roast beef?"
"My sausage burrito could really use some second hand gravy!"

Grave hand 

That random hand you have when you cuddle your significant other, that just sticks out looking like a zombie coming from the grave.

When I cuddle my girlfriend I get grave hand.
