A tornado filled with sharks capable of vast amounts of hilarious destruction! Also a movie. Has many uses in common venacular:
Bob: Come at me Bro!!
Dave: Oh I'll come at you! I'll come at you like a Sharknado!!

A "sharknado" derives from a combination of both the words "shark" and "tornado". It is exactly that: a shark tornado.
Did you hear? Cory just witnessed a sharknado.

1. That one movie that was mediocre at best.

2. The sexual act between a women and multiple predatory men, in which the multiple men, while butt naked, take their dicks and swing them around like helicopter blades. They then proceed to slap the female in they face with their dicks, while three random guys fill all three of her orifices, (mouth, vag, and anus). They all take turns until they're all ready to cum. They all proceed to bust a nut on her in unison, creating a Cum Tsunami. This action shares some many similarities with an orgy, however, it is quite more intense.
Tod: Did you hear what happened to Stacy?
Terry: No. What happened?
Tod: Sounds like she let five guys do the Sharknado on her...

A euphamism for any kind of sexual act, wherein lingo for typical movie-goers substitutes language normally associated with whatever sex-act is being talked about.
"Hey man, did you catch that Sharknado marathon on TV last night?"
"Huh? What are you talking about?"

"Well, let's just say I was going through the TV guide, and decided to invite Caroline to come and watch Sharknado."
"Whoa, seriously? Nice! Up top!"
"Haha, thanks man. And how about you? Rewatched Sharknado lately?"
"Nah. I spent my entire evening in Sea-World yesterday, at the petting-tank."
