Rejected Smash Character

Listen up, buttercup. This joke is for intellectuals. See, "holy cross" refers to the cross that Jesus died on. Now, Smash, that's Super Smash Bros., a video game where Nintendo characters beat the crap out of each other. So, the joke is that Jesus on the cross is like a rejected character from the game. You probably only play mobile games on your mom's phone, you silly goose!
