Catchy words are important in a DJ’s jingle because they help to create an earworm effect that will keep people hooked on the song. Some examples of catchy words that a DJ might use in their jingle include:

“Bumpin’, groovin’, gettin’ down”
“Rockin’, rollin’, never stoppin'”
“Fun, fun, fun!”

These words are all designed to get people moving and keep them engaged with the music. By using catchy words, a DJ can make sure that their jingle is stuck in people’s heads long after the song is over.
