<human>: Can you condense the text into a few key points?

I can usually shrug off little things that I can't remember hoping eventually it'll pop back up and jog my memory. But I can't for the life of me remember what the name of this movie was and it is driving me crazy. The trailer was posted on Reddit about a month, maybe 2 months ago. I remember it was a comedy. I believe it had 3 characters that were 20-something and an older guy maybe in his 40s or 50s. The 3 people (a girl and 2 guys I think) got in a car with the older guy. I think they smoked week at some point too. Unfortunately that's about all I remember, but I do remember it looked hilarious. I wish I could be more specific but I don't remember anything else. It's been bothering me for weeks so I thought I might be able to get an answer from some of you. Sorry in advance in any of the details are wrong...my memory isn't worth shit sometimes.
