Sometimes the best response is an animated GIF.
BBK/BRNK is an anime about a group of kids with living weapons (that combine to create a giant robot) going on an adventure to save the world.
It is also a series that, thanks to its smart directing and CG animation, provides GIFs for nearly every situation. For example:
When someone needs to shut up.
When you make an argument-winning point.
When you have the perfect counterargument.
When you really messed up.
When you notice someone’s fly is down.
When you’re peeking at something and you know you shouldn’t be.
When you can see what’s really going on here.
When you do not want.
When you really do not want.
When you’re terrified beyond the capacity for rational thought.
When you want someone to look “up here.”
When someone needs to be rejected.
When you just can’t hold it in anymore.
When you find someone who shares your fetish.
When you’re fast friends with someone you just met.
When you learn that you might have been a bit hasty.
When it’s time to panic!
When it’s time to panic! …Oh wait, maybe not.
When it’s time to rock out with your bad self.
When it’s time to kick it up a notch.
When you’re sick home while everyone else is out having fun.
When someone stole your ramen.
When someone stole your booze.
When you’re just feeling cool as fuck.
When you think you are cooler than you really are.
When you’re exactly as cool as you think you are.
BBK/BRNK and BBK/BRNK: The Gentle Giants of the Galaxy can be viewed for free and with English subtitles on Crunchyroll.
