Sharknado 4 trailer: Strippers fight sharks with their greatest weapon - their own crotches

'What happens in Vegas stays in Vegas. Unless what happens, is this...'

Sharknado is officially back.

Not that it ever really left, though; with the most baffling cinematic franchise in existence perpetually thundering onwards like a runaway train. Filled with sharks. Whatever metaphor you can attach to this film, it automatically must be filled with sharks.

And with the arrival of the first trailer for its fourth installment, it looks like the Sharknado franchise is actually starting to lean towards the Scary Movie realm of movie parodies.

First off, we've got the full title. Sharknado 4: The 4th Awakens, which would almost be a clever joke if there weren't already an annual fan celebration based on that same pun.

Then we've got the distinctly Magic Mike-looking male stripper seen fending off a shark the only way he knows how; by crotch-slamming it into oblivion. Never stop doing you, Sharknado.

Sharknado 4: The 4th Awakens stars Tara Reid, Ian Ziering, Gary Busey, David Hasselhoff, Stacey Dash, and Vince Neil; debuting in the US on Syfy 31 July, 8/7c.
