When you take a dump in a shoebox, or other innocent looking receptacle. You then leave it somewhere where it blends in with its surroundings. The horrible smell emanating from the box makes people have to search through everything to find it.
Ericha really pissed me off, so I took a phantom dump in a shoebox and hid it under her bed. She'll probably find it after searching around for it later.

While on a dinner date, secretly jerk off into your hand. Wait until the girl gets up to use the bathroom, or distract her in some way. When she's not looking BAM! into her salad/food. Works particularly well if she's having fettuccine alfredo or some similar dish.
I was out to dinner with my girl last night. She got fettuccine alfredo, so when she wasn't looking I pulled a phantom gourmet and threw a fist full of cum in her food. She never figured out why the alfredo sauce was so salty.

the idea of being in denial, for an extended period of time, that a movie you've watched was bad or disappointing, especially after having highly anticipated it; after this period, you eventually admit to yourself that said movie was, in fact, not as good as you'd thought.
"My most recent case of phantom menacing was after Jurassic World, where I remained in denial for a good half year before finally coming to my senses."

Someone who doesn't finish their alcohol before they open a new can/bottle and then doesn't admit that the unfinished drinks are theirs. This results in numerous half-full drinks left lying around.
John: "Who keeps leaving these half-full bottles around?"
Ben(Phantom Sipper): "Not me."
John: "Someone is a phantom sipper!"
Ben(Phantom Sipper): "Not me."
John: "Someone is a phantom sipper!"
