Word Art in Google Slides allows the user to type in their terms or sayings and it will "make it look cooler" according to my 7 year old daughter.
There are limitations with Word Art - but the user can change the color of the body of the word (Fill color), the color of the outline of the word (Line color), as well as the thickness of the line (Line weight), and how the line around the word looks (Line dash).
You can also change the font of the word art as well - see the 2nd GIF.
