Tofu Cracker
Used an an insult against a (typically white female) self proclaimed "health guru". Usually obsessed with crystals, energy healing, and follows an extreme form of veganism (may go as far to shame any meat eater).
Health guru: "Make sure to realign yourself with Mother Earth's core every five minutes!"
Everyone else: "Ok, tofu cracker."
Everyone else: "Ok, tofu cracker."
