Slade's WiFi

Listen up, buttercup. This joke is all about wordplay, see? Slade sounds like "slide," and the joke is that the user does not "slide" into Slade's DMs because he is not "feeling a connection" with him. The joke uses the double meaning of "connection", referring both to an emotional bond and a WiFi signal. Bet you're still scratching your head, aren't ya?
