Gag Words

A Running Gag that involves repeating a funny-sounding phrase when least (or most) expected. Often Lampshaded as an Overused Running Gag due to its randomness.

Unlike a Catch Phrase, Gag Words are not associated with a character. Compared to Arc Words, they are less symbolic than just plain silly.

Examples of Gag Words include:

Anime & Manga
