"No, she's absolutely right," said Zeb, patting the enormous pistol at his hip. "This is a penis substitute. After all, if I could kill at a range of thirty meters with my penis, I wouldn't need to carry this thing around, now would I?"
Guns, cannons, swords, daggers... they're all penises.
After all, most of them are vaguely phallic (any object longer than it is wide = phallic), they penetrate human flesh, and killing people is a sign of virility. In the case of guns, they even "ejaculate" bullets, while swords tend to have the reminiscent shape, with the long blade section and the thicker hilt guard in the bottom, and are usually held at around crotch height — and, in some cases, kill with a thrusting motion. So it's not much of a surprise that weapons in general are a very popular source of phallic symbolism, if not the most popular.

Yu Yu Hakusho example: Sensui's Kazuya personality's gun-arm. What he does to Yusuke with it looks ONE HELL of a lot like Prison Rape. This is lampshaded in the dub:
Kazuya ('pressing gun to Yusuke's face'): "Open your mouth, and close your eyes..."
Majin Tantei Nougami Neuro has a killer keep a ridiculously long revolver down the front of his pants. The guy is a huge parody of Eagleland attitudes, so he's not the most subtle person around.
In Gamaran there's Zenmaru's great katana, Sadanaga: he's extremely proud of its size and power, gets annoyed if anyone comments on it and he's a bit flustered by Shingo's Onidachi (a 4 meter long spear), stating that's even bigger than his sword....
Also, where Mayuri Kurotsuchi keeps (his? her?) sword.
In Black Cat, after smashing Train into the wall, Creed rants about how his disappointment and anger toward Train has caused his (imaginary) sword to grow enormous in strength and size. While holding a rose between his teeth, no less.
Naruto and Sasuke have a lot of Ho Yay between them. And Sasuke regularly attempts to kill Naruto by stabbing him with his sword.
Used hilariously for a supremely ridiculous villain in Doom Patrol, who was ridiculed all his life for having a small penis and thus built a giant cannon to attach to his crotch and called himself, what the hell, Codpiece. The Nightmare Fuel comes in when said super villain is defeated by a transsexual heroine... who has the power to dissolve objects.
Towards the end of Preacher, Herr Starr develops the disturbing (and hilarious) habit of holding his gun over his crotch and repeating "Doom cock...Doom cock..."
When Superman rescues Lana from Lex Luthor's mooks in an early Post Crisis comic, he faces down a Mook with a huge bazooka and asks "Overcompensating for something there, fella?"
Bonnie & Clyde has a very sexually charged scene where Bonnie checks out Clyde's gun.
In From Dusk Till Dawn, the character Sex Machine has a "crotch gun," basically a codpiece with a gun on it.
It also made an appearance in the Mariachi's guitar case full of guns in Desperado, with the Mariachi commenting that it saved his life once, but we never see him use it.
Tank Girl has a moment loving on the gun of the tank she ganks from Water Power. To the tune of Shaft, no less.
And later on, explicitly called out as she rides the cannon up to the window of a truck. 'Feeling a little inadequate?'
In the Line of Fire. When Agent Horrigan (Clint Eastwood) misses a jump and ends up dangling from a rooftop. Mitch Leary (John Malkovitch) pops up overhead, prompting Horrigan to take aim despite his failing grip. Leary teases Horrigan's pistol a bit before deciding that he'll take care of him later, and helps Horrigan to a nearby fire escape.
That scene in Videodrome where James Woods grows a vagina and then starts masturbating it with a gun.
In The Pirate Movie, the Pirate King is asked "Is that a knife in your pocket or are you just pleased to see me?" It turns out it is a knife in his pocket, as he pulls it out and throws it into the wall beside the woman's head. However, he then demonstrates that he is also pleased to see her.
In the first dream level of Inception, Mr. Eames produces a grenade launcher from his Hammerspace, blows away a group of projections and says "You mustn't be afraid to dream a little bigger, darling." Persons who do not feel that this implies "I can also do this with my penis" are hereby commended on the cleanliness of their minds.
Psycho features the infamous shower scene—the phallic-shaped knife, repeatedly stabbing Marion. Not to mention the killer having sublimated his sexual repression into murderous urges.
In the Scream movies, the serial killer targets young women, simultaneously acting seductive towards them and trying to stab them with a knife.
Used deliberately and disturbingly in Six Feet Under when a carjacker forces Dave to suck on his gun and threatens to shoot him with it before running away. In a show where Anyone Can Die, it seemed like he might pull the trigger.
In the episode The Gun of M*A*S*H, Frank steals a gun. Margaret also gets an orgasm when Frank shows her the gun (she then doesn't know yet that Frank has stolen the gun).
Played with in Burn Notice, where the girlfriend of the not-too-bright son of the villain of the week gets the hots for Michael.
Debbie: I ... want to see your gun. Michael: Okay, that's not my gun. Not my gun.
Mitch Benn in the video for "Happy Birthday, War," as a parody of the Cher video.
Kings of Metal by Manowar. The line "We got the biggest amps, man they blast." But the whole song, as well as Manowar image in general, are an example of this, or more suitably, Not compensating for anything thrope. As those thropes are close, in case of Manowar, they complete each other.
The band Machine Gun Fellatio.
The Ludo song Go-Getter Greg: "I'm a go-getter guy with a gun on my hip, I'm just searching for that someone to be firing it."
A quote from Kreia about the lightsaber in KotOR II: "For the male, it seems to have inordinate importance. But we shall leave such male preoccupations for philosophers and cultural historians."
When visting the Citadel for the first time in Mass Effect, the crew of the almost tiny Fragile SpeedsterNormandy is deeply impressed when passing The BattlestarDestiny Accension, the biggest warship in the entire galaxy. Which leads pilot Joker to one of his usual moments of snarking:
Ashley:"Look at the size of that ship!"
Joker:"Well, size isn't everything."
Ashley:"Why so touchy Joker?"
Joker:"I'm just saying: You have to have firepower, too!"
He gets to prove it too - He and his Normandy gets to deliver the killing blow to Sovereign.
A nice Renegade response from Female Shepard at Omega from Mass Effect 2:
Merc Recruiter: Well, aren't you sweet? You're in the wrong place, honey. Strippers' quarters are that way.
Shepard: [pulling out her gun] Show me yours, tough guy. I'll bet mine's bigger.
There is a clip from the Swedish movie Kopps where a police officer throws his gun into the air, opens his pants, catches the gun in the open fly, then buckles his belt over the gun. He then guns down two criminals using pelvic thrusts. Then takes out the third by hacky-sacking the gun and kicking it into mook's face.
An over-the-top feminist review of Portal uses this in a ridiculously contrived analysis regarding the misogynist implications of shooter games. It then praised Portal for it's feminist aspects, that included the portals' semblance to a vagina.
Literalized in It\'s Always Time: Strawberry Banana (aka SB) (she's made of Jell-O. It Makes Sense in Context.) is a woman with a penis. A detachable penis. And when she detaches it, it turns into a sword.
