Cactus mode is when you live in an ingredient household, and only eat one easy to make meal over and over because they’re too lazy to actually cook something.
dude 1: Hey what should we have for dinner
dude 2: We should have Mac and Cheese
dude 1: we’ve been eating Mac and cheese for the last week and a half, pick something else.
dude 2: I can’t, I’m in cactus mode, and can’t cook anything else.
