look up any word, like the eiffel tower:
 
3.
An indirect or subtle -- in the case of urban slang, not often subtle as so -- usually derogatory implication in expression; an insinuation.
The foundation of urban slang rests on the pillars of innuendo-laced phrases most of which were invented by the lower class of society.

Anything that gives off a wrong idea, or sick minded thought
George: "And I'm good at banging. My peg's hard isn't it Zippy?"

Zippy: "Well of course it is, Your peg wouldn't go in if it was soft."

Geoffrey: "Let's get back to Bungle's twanger."

Bungle (excited): "Oooooh Geoffrey, we could all paint our twangers couldn't we?"

Jane: "Ooooh yes, and I was banging away all last night with Rod and Roger."

Roger (looking sad): "Yes, but it broke my plucking instrument."

Geoffrey: "Never mind Roger, let sing the plucking song, come on

everybody get your instruments out."

Rod (to Jane): "Do you want to blow on my pipe while I'm twanging away?"

Jane: "Oh no Rod, I was blowing a lot with Roger last night. But would you

like to play with my maracas?"

Zippy: "No, let's just pluck away with our twangers."

Bungle: "Yes, it doesn't matter what size your twanger is."

Zippy: "I've got a big red one."

George: "I've only got a tiny twanger. But it works well and I like to play with it."

Subtle or not-so-subtle implications to sexual activity in an otherwise seemingly innocuous phrase. It's excellent if you have a dirty/weird sense of humor.
Some luscious examples of innuendo-

Q: "What's brown, oval, hairy, delicious, and contains a thin, whitish liquid? It begins with 'c' and ends with 't'."
A: "Cocoanut"

Q: "What does a cow have that a woman has only two of?"
A: "Legs"

Q: "What does a man do standing up, a woman do sitting down, and a dog do on three legs?"
A: "Shake hands"

Q: "This thing is long, thin, has a collection of bristles on one end, is enjoyed by both sexes, and is inserted into a warm, wet orface. When it's removed, the cavity that it was placed into is filled with a thick, white liquid. What is it?"
A: "Your toothbrush"

"I'm a pianist. I love to play with my organ, too."

"The meeting just started. Are you coming?"

"I have to pick up prescriptions for the kids. I need MYCOXAFLOPPIN, MYDIXADRUPIN, DIXAFIX, and IBEPOKIN."

-"What type of whale was Moby Dick?"
-"Um... a semen whale"
-"... (snickering)"
-"Don't you mean sperm whale?"

"What I hate about cleaning (replace the word 'cleaning' with the word 'sex') is that I'm never sure where to put it. I have to find a place where it looks nice. And I also have to get down on my knees and go where it smells bad."

"'Pet My Pussy Barbie' comes with her cat and everything you see here."

And so the town cheered as the girl stuck the oil drill into the crevice.

the ultimate solution of built-up sexual frustration which means doing things like:

1. putting the microphone between your legs right onto your crotch while gulping water and touching the mike to imply blow job to your boyfriend
2. sitting on a couch spreading your legs, then staring at your crotch and looking up at your boyfriend smirking yet again implying blow job
3. gazing at your boyfriend while inserting each of your fingers into your mouth slowly in order to fucking turn your boyfriend on and make him suffer from restraint
Ex: Fan 1: OMG! Louis was singing and Harry just walked over to him and showed his microphone right in front of Louis' face!!! Louis turned around and I think I heard him say: "Later!" What the fuck does that mean?

Fan 2: Hahaha doing innuendo. Little Harry's being a horny ass again!

Fan 1: Dude, Harry's not gay. He likes girls.

Fan 2: You must be new. He's been taking it up in the ass all along and he loves dicks. Okay bye!
