What is annoying is an opinion. Some of my suggestions may have been loony. Some weren't.
I'll just say the ones I think are important are:
/cross arms
/hands on hips [along with the /cross arms, this is for people who are bored, tired, assertive, have attitude, and many other qualities.]
/wink [lovers, friends, playful people, many do it.]
and /lay ears back [can't tell you how many enki's I've seen do this]
Those are actually things that I see RP'd alot, so they should be considered for implementation.
