Awkward Cactus
The action of holding both arms out in upside down 90 degree angles (like a cactus with upside down arms 🌵) during an awkward or uncomfortable situation when you don’t know how else to respond. Usually paired with an uncomfortable smile 🙃. This is especially used by socially awkward people.
Friend: you look cute today.
Me: 🌵🙃
Friend: you look like an awkward cactus
