The most ridiculous thing, I find, is that giphy on Slack prints your search term as well, so others can read it.
That completely takes the fun out of the *.gif for me.
For me, seeing the original search term only increases the hilarity. It often leads to amusing juxtapositions between what the sender wanted to search and the gif they chose, or maybe they included an in-joke or excessively detailed description of something, etc.
That’s one of the main reasons I don’t use giphy on slack. I’m with you.
