Attempting to say goodbye and failing as a quick departure is made.

Missing the chance to say goodbye to someone leaving, usually witnessed by others who will tease and taunt you for it.
CyAdora failwaves at her friend who left the chatroom in a hurry. Then was made fun of for 5 minutes for being slow.

I watched my bf sitting on the bus and was waving goodbye. As I turned around I realized he missed my full moon failwave. The old man sitting next to him had a big smile as I looked back.

After I got home from the concert, I checked my mobile to see all of my friends had failwaved to me before I left.
