A **symbol** when one wants to denote sarcasm in a written form, without being misunderstood.
Lawrence didn't want Edo to misunderstand his text message, so he used a sarcasterisk. "Hey Edo, **thanks** for recommending Glitter! I really **enjoyed** it. Feel free to suggest more **classics** to me."
a combination of sarcastic and attitude, that annoying attitude that a lot of girls have, unnecessary sarcasm, so sarcastic that you dont know when they are being serious or sarcastic.
boy: can i have a kiss girl: yes
boy: are you serious?
girl: yes
