Godspeed
Here’s a tattoo that someone got to commemorate their best friend. Apparently, the OP had lost their best friend recently, and they decided to dedicate a portion of their body as a way to remember how much their friend meant to them.
Now, there’s no way to tell for certain whether the OP and their good buddy actually built a campfire on the moon and looked down on the Earth. However, they probably shared a special moment together, which made them feel as if there were nobody else in the world but the two of them, sitting side by side and drinking bottles of beer.
