An act devoted to others' welfare or interests and not one's own. A self sacrificing act, that benefits others... performed by a truly selfless person. At a time when people need it most!
Person 1 - "My friends are living their lives too dangerously. Booze, drugs... Someone needs to show them it's not a sustainable lifestyle"

Person 2 - "What we need is a selfless act... They just need to see that you can die from living that lifestyle. Looks like it is up to me!"

(Person 2 has a near death experience after jumping off a balcony. person 2 survives with some lasting injuries. But due to that selfless act. His friends see the error in their ways, and change their lifestyles)

Get the Selfless Act mug.
When you do something that has no actions on yourself. Like if you jump off a building, no one cared so you're self-less.
When you are the only one that likes your definitions that is considered a 'selfish act'. I mean selfless act. My bad.
