There is this girl at my university who is a complete tease. She always arrives a bit late to lectures, dressed slutty and walks in front of the whole audience to find a seat. Every fucking time. She has tons of orbiters that brings her coffee, messages her neck etc. But gets nothing from her. We have friends in common and are thus at the same parties etc from time to time. As of now i completely ignore her, I don't look at her or talk to her. Is there anything else i can do?
