Basically, fake tears.
Many actors can be relied on for their facial expressions, their voices, their looks, muscle, hair, what have you. But to be able to cry on demand? That is a rare and powerful gift.
But the power to do so, without sincerity, in the hands of the Manipulative Bastard? Heaven help us all.
This trope gets its name because crocodiles can and do produce tears, but not out of emotion as humans do; it's simply a way of getting rid of excessive salt (something that many seabirds also do). 14th century travel stories had it that they cried to draw in their prey, or as a false show of guilt or grief over the prey they were eating, and the usage has carried over to human displays of false tears over the years.
This trope is not limited to just the Manipulative Bastard, however. Children "crying" to get what they want is Truth in Television (see #6 on the Cracked list Six Shockingly Evil Things Babies are Capable Of.).
Often a key part of a Wounded Gazelle Gambit.
- This trope is referenced in Ouran High School Host Club — all the male hosts seem to cry at the drop of a hat, in order to create 'emotional' scenes, and Haruhi soon stumbled on the explanation - they all use eyedrops to induce tears, though Tamaki claims he doesn't - a true host can cry on command without needing such aid! (Towards the end of that episode, Haruhi accidentally pushes Tamaki into some fairly drastic action with some surprising tears - which, as it turns out, was caused by a loose contact-lens.)
- Blue when confronted by Ho-oh in Pokémon Special.
- There is a literal case as one of White's agency Pokémon, a Sandile, has the specific purpose for crying for any tragic movie scene.
- In the anime, a Teddiursa pulls this by framing Chikorita and Totodile for stealing food and beating it up. Actually, said Pokémon were trying to stop it. But when Teddiursa tries this with Bulbasaur, Ash and his friends don't fall for it this time.
- Also in the anime, Shamus reveals he uses this tactic whenever he abandons a Pokémon so that they'll leave him alone.
- One Naruto Non-Serial Movie had a big-name actress use eyedrops to create fake tears (because she'd become such a Broken Bird that she was now an Emotionless Girl).

- An episode of Paranoia Agent features an Internet suicide pact between two men who are shocked to discover that their third member is a little girl. When they decide to leave her behind, she tries to guilt-trip them by crying, even though there are no visible tears.
- Kokinchan from Anpanman constantly uses these. As an added bonus, if other people are hit by her tears, they'll start crying uncontrollably. She's a little girl, so she uses these to get what she wants, or just to get other people to start crying. When her needs are satisfied, she'll stop crying at the drop of a hat.
- Kanna did this on her first day of school in Miss Kobayashi's Dragon Maid in order to get Saikawa to drop her Tsundere act and become friends with her. She dropped the act when Saikawa offered her some candy.

- In Lex Luthor: Man of Steel, when Lex sets off Hope's self-destruct system, he narrates "If only my tears didn't brand me as your Judas", but there are clearly no tears in his eyes. Notably, the only time we see any tears is when Superman is there to see them.
- In Violine, Muller does this while threatening to kill Redder.

- In Catwoman, our heroine confronts the villainess in her home, who reveals her husband's dead body which just so happens to be covered in deep scratches, right before she triggers an alarm and cues crocodile tears, screaming "IT WAS CATWOMAN!"
- Referenced in The Man Who Knew Too Little. Wallace says something that offends Lori, and she cries briefly. Wallace, who thinks everything is a play and Lori is an actress, marvels at what he thinks is the ability to cry on demand.
Wallace: Was that a tear? ...How do you people do it? Did you... poke yourself in the eye? Or are you thinking right now: "My dog is dead."
Lori: What's the matter with you? Are you enjoying this?
Wallace: Enormously. "My dog is dead." [pokes himself in the eye] "My dog is dead."

- The Big Lebowski - Mr. Lebowski summons The Dude to his mansion, and gives him the job of delivering bogus ransom money to the kidnappers of his trophy wife. He sits by the fireplace in solemn tears, telling The Dude "Strong men also cry", masking the fact that he's pulling a scam, using foundation money for the ransom and keeping it for himself.

- One of Tom Holt's near-interchangeable protagonists (Paul Carpenter, IIRC) at one point remembers how, when left to play with a young cousin, the little rodent would at the first hint of boredom burst into tears and run out crying "Mummy, he hit me!" Since most of Tom Holt's protagonists are Butt Monkeys and/or Chew Toys, this is pretty much standard.
- Played with in the children's book Big Max by Kin Platt, after Big Max and the King of Pooka Pooka have escaped from a literal crocodile.
"Look, he is crying," said the King. "That means he is sorry."
"A crocodile's tears can fool you," said Big Max. "He is crying because he did not have us for dinner."
"Don't remind me," said the crocodile. He cried some more.

- The "North Korean Photoshop Tutorial" by CollegeHumor has Photoshop Project Manager Brian O'Neil Hughes do this to a crowd photo from Kim Jong-Il's funeral:

We'll just droop these a jowls a bit, okay. Just drag this frown down here. Yeah, just really make this woman look like a rotting misery pumpkin. We'll take the soft brush here and add in a few tears.
