The new Robert De Niro/Zac Efron comedy film "Dirty Grandpa" has just released a red-band trailer for those who want to see what the real content of the movie will feature. Here is your first warning -- do not watch this video with the sound turned up if you are at work or around children.

The new trailer features mature content, mostly in the form of language. Fans of De Niro know all too well what his favorite word is, especially in movies like "Goodfellas" and "Casino."

So now that Grandpa (De Niro) has been freshly widowed, he has decided to live like there is no tomorrow. That means involving his grandson (Efron) in a scandalous journey down to Florida for Spring Break with young ladies who are ready to party.

This is something the grandson opposes adamantly, considering he got tricked into making the trip under false pretenses to start with. But, when he and Grandpa meet a few ladies at a truck stop on the journey, the testosterone level gets jacked way up and from there on it is nothing but sexual references in the crudest form.

"You're grandmother told me to get back out there," Grandpa tells him when he fervently rebukes him for his actions.

Grandpa also makes a comical reference to his pink Mini Cooper that he pulls up to drive him away with, referring to it as a "giant labia."

He also has to rebuke Grandpa's attempts to convince him not to marry his fiancé, instead living a little before he settles down.

"If you marry her, you're gonna be sleepwalking through the rest of your life," Grandpa said.

There are also several scandalous moments between De Niro and actress Aubrey Plaza, which you may want to make sure no one sees you watching.

The film will premiere in theaters on Jan. 22, 2016. Watch the trailer below.
