reaction (deleted)

A reaction is a pose that an entity does when they've seen something they shouldn't, something that genuinely surprised them (or downright dumb) or they get caught in the act (embarrassment, for example) among other things.

An example reaction scenario would be an male entity walking in on another female entity which is getting changed in the bathroom. Depending on the character's personality, the male could get a kick to the groin or a slap across the face. An other example of a reaction can be seen in Danbooru post #1903402.
