Dylan (Justin Timberlake) and Jamie (Mila Kunis) are both burned out on serious romance. After meeting at work, they decide to add a "benefits" arrangement to their friendship—no strings, no jealousy, no falling in love. Of course, things don't go as planned.

When you hear "FWB," you might think of modern dating slang. But the 2011 movie Friends with Benefits turns that phrase into a funny, heartfelt look at what happens when two people try to skip the "feelings" part of a relationship.
I notice you're asking for a "blog post" about the "FWB full movie." However, "FWB" is a broad term—it could refer to Friends with Benefits (2011 starring Justin Timberlake and Mila Kunis), a different film with a similar title, or even a non-mainstream or regional movie.
