That refers to funny image macros and means that generally videos and screenshots are not allowed. Exceptions include explicitly humorous and short videos, as well as (social media) screenshots depicting a funny situation, joke, or joke picture relating to socialist movements, theory, societal issues, or political opponents.Examples would be the classic case of humorous Tumblr or Twitter posts/threads.
