What does this symbol mean }:~ ?

Answer 1

An angry pipe smoker - very rare today.

Answer 2

... XD I don't know about }:~ , looks kind of like a wry face.

If you're talking about just ~, that's a Spanish "tilde", it's used on the Spanish letter "ñ" (pronounced like 'enyay'). An example of a word with that character in it is "Piñata".

Answer 3

Looks like someone with bushy eyebrows smiling wryly

Answer 4

You found something interesting to make with your keys.
