The GIPHY slackbot is a bot user for slack that will reply to certain commands with a Gif from GIPHY
If you want to access the GIHPY slackbot, you may @ it in any channel it has access to, followed by the name of the Gif you want. If you want it to be a random Gif of that type, you can start with the word random. The Gifbot will post the gif it recieves immediately after. Watch the demo here
