The oldie but goodie "KILL IT WITH FIRE" and the variants spawned thereof (IE: "Nuke it from orbit!" or the less well known "Kill it with a crowbar").
I like some other memes of course, especially as they occur to me if they seem relevant to whatever I'm doing. But yeah, "KILL IT WITH FIRE" is the expression and meme I keep coming back to.
Similarly, if I find someone particularly unpleasant (most common with fictional characters), I think of the "Go die in a fire". Less a meme, more of an indicator if my intense dislike. A burn that involves the suggestion that they actually burn.
This forum is dank guys. But we can do better. To help in our cause, I decided to invite the Supreme Meme Lord, the LegendaryIlluminati Master, the MythicalAir Horn Composer, Daddy Dank himself, Snoop Doge.
Make sure you share the good kush with him. He deserves it. Now people, smoke that thinking weed. We've got memes to make.
