Unfunny 

Someone like Lily Singh, King Bach, or Hannah Stocking who default to bad sex jokes, dumb faces/noises, or orange man bad jokes. Unfunny is a word that can apply to others who use this same humor, or it can be used to describe any bad meme, video, gif, etc.
The gif shown below is a gif of Lily Singh, the unfunny one listed above.

Unfunny Jokes

Unfunny jokes are -69/10 jokes, like this one. You really aren't supposed to use them, seeing how many people who write these are in Gen Z. These can be ranging from Teen Titans Go to every dead meme in existence. They also are very awkward, because saying sus can make your social credit drop from 793 to -sideways 8.

Kids in the Hall, a sketch comedy (and I use the term "comedy" loosely here) by some no-name flapping heads.

Kids in the Hall is as unfunny as it gets; placing a close second is Dave Foley himself.
