I'm sure most of you know about punctuation marks.

But here are two of the lesser known, more modern ones.

The interrobang.

Just by looking at it I think you should know what it's used for. Basically for when you wanna ask a question in an excited manner.

The sarcmark.

Short for sarcasm mark. Used to show that the sentence is meant to be sarcastic. Though if you're usually a sarcastic person there'd be no need to use this mark. People would already know that you're being sarcastic.
