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.
