Veg out

👉 It means to completely relax and do nothing, usually in a lazy, low-energy way — like watching TV, lying on the couch, or scrolling on your phone.
👉 The idea comes from “acting like a vegetable” (not moving much).

• I’m so tired — I just want to veg out on the couch tonight.
• We vegged out all weekend and didn’t do any chores.
