When we fuse two words we can create a new word, and sometimes a new concept. We call such words portmanteau words.
Not long ago, I heard the portmanteau word slacktivism for the first time.
Slactivism: half-hearted activism
We participate in slactivism by posting images or text on social media without taking further action.
Not long ago, I saw a bumper sticker mocking slactivism. It simply said. “I support the current thing.”
Slactivism, a portmanteau word, is a combination of slacker and activism.
