Dirtyroulette c2c guys meaning of hand signals?

[calf]

So I use dirtyroulette.com for fun and noticed the guys use specific hand signals. Anyone know about this? I haven't figured out the meaning yet but here's my guesses:

a) Horizontal OK sign - Thumb and 1st finger in a circle, held horizontally, sometimes moving it in up and down motion
- "You have a thick cock"
- "Stroke your cock"

b) Come to me sign - palm up, fingers curling in as in a "come on over here" motion
- "Cum for me"

c) 1st finger (pointing downward) drawing a circle in the air
- "Turn around for me and show your ass"

Those are the 3 that I remember seeing repeatedly, has anyone else seen these and understand them? Thanks, haha.
