When someone goes deep into the explore page on Instagram to find the best memes
Friend 1: Check out this quality meme.
Friend 2: How did you even find this?!?
Friend 1: I went deep meme diving.
The action of diving into the deep web to steal some dank memes and/or get some meme material.
Dude, I went meme diving the other day and came back up with some dank material.
