An uptight lawyer who is about to get married takes his recently widower grandpa on what he thought would be an average day on a golf course. What could possibly go wrong? A lot when you discover that the man who you thought was a well-respected old fashioned person turns out to be a foul mouthed curmudgeon who hasn’t had sex in 15 years. Such is the basis for the film Dirty Grandpa starring Zac Efron and Robert De Niro.

Lionsgate has just released the newest red band trailer for Dirty Grandpa which features all sorts of devious sex acts, troublemaking, drug use, and other explicit things that can be considered NSFW. So break out those headphones, and make sure no one is watching, because you can watch the latest red band trailer for the film below.
