How do 당신 usually greet your friends?

Depending on which friend I am talking to it's either: "hey biatch" 또는 "Ew who invited you?" They know I am kidding when I do that. If they are new 프렌즈 though it's the normal hi how are 당신 greeting.

Depending on who it is.

1.If they don't mind. I casually insult them. (In a joking manner)
2.Casual greetings (such as hi,etc)

Either 암캐, 암 캐 또는 babe tbh

With a super-secret long handshake 👐 we invented just for ourselves! 😆

usually 의해 saying hi and if I haven't seen them for a while,I hug them

In person - I usually either say Hi 또는 nod a hello 또는 just wave.

On line -
- E-mail - I am usually formal - like a letter I start with Dear _____.
- Messaging - I just go into the conversation on what I am contacting them about - usually wishing them a Happy Birthday, etc.
- 팬팝 - it differs, but usually just go into the conversation - no formal greeting.

hi
hello
hey
whats up
yo
haha what 당신 looking at
ah 당신 again ..

I either say their name is some ridiculous way 또는 I just jump right into the conversation.
