A way to express one's confusion. Often used when someone does something too stupid to comprehend. Often help for up to three seconds but can be shortened or lengthened based on how stupid the person was.

It is not uncommon for people to take their dominant hand, bend it forward, place it over their chest, and wave it as if they were having a seizure.
