Yo yo yo yo? Nope. :b It shows Korean people prefer indirect expressions. I think it's cooler than saying 'I'm crying' or 'I'm sad'. Try to think of it as a facial expression.
ㅡㅡ shows the edges of the eyelids, ㅣㅣ shows tears running down from someone's eyes. Therefore ㅡㅡ + ㅣㅣ＝ ㅠㅠ There are more stuff like this, ㅜㅜ, ㅡㅜ, ㅠㅜ, T^T, T_T, ToT, ┳━━┳ ___ ┳━━┳
. (a dot) : Mouth ⇒ ㅡ.ㅡ .. : Nostrils ⇒ ㅡ..ㅡ
, : A runny nose ⇒ ㅡ,.ㅡ (Think some morons are likely to sniffle on TV as a cliche.)
If you use ㅡㅡ+, you suggest you glower at the looker. -_-a shows you scratch near your ear, I guess it suggests you tilt your head sideways or you think over it. ; ⇒ The sweat ^^; ^^ㆀ ㅡㅡ; -_-; - -; ㅡ ㅡ; ─── __ ───ㆀ
* : blushed cheek or bright eye
*^^* (_ _* ( * ─ * ( *.*
^0^, ^ㅇ^, ^O^, ^▽^, (￣ ▽￣ , Bowing ⇒ (^^) (_ _) ㅋㅋㅋ(크크크), ㅎㅎㅎ(흐흐흐), ㅍㅎㅎㅎ(프흐흐흐) ; Laughs. ㅋ_ㅋ, ㅎ_ㅎ, ㅍ_ㅍ and so on, personally I feel I'm going to beat who uses these stuff because it seems to sneer at me. X）
(_ _)zzz suggests I'm sleeping or I'm sleepy, ＠_＠ suggests something makes my eyes spin or I feel dizzy or feel tired.
I don't use ^^ to my close friends. I don't know others think like us, at least I and my close friends think ^^ is a facade between close friends. I guess it comes from a certain belief that smiling people could hide something. Ah, when ^ is used with ─ ─, it(ㅡㅡ^) suggests the user raises his/her eyebrow. ㅇㅅㅇ ㅇㅁㅇ ─ㅅ─ ;ㅁ; ;ㅂ; ← Just imagine.
Before I got the meaning of lol, I had been curious why they hold their arms up(ll = arms, o = one's head), lol
