Trashtag 

A trending that blew up in 2019 with the goal of making our planet healthier.

It's basically when you take a picture of a polluted place (as a beach for example) before and after cleaning it. It's usually posted on Twitter or Reddit with the tag "#trashtag".

Tom : Hey, did you see the trashtag Peter made in our local abandoned park? That's so nice from him!
Laly : hell yeah, I guess I'm gonna try to go clean that messy place in the city too
