She's a constant pain in the ass, and literally has this routine of making kisses noises when she needs your attention. The fucking bitch even half-smiles when doing it because she knows she's just messing with you. It's like she takes the whole "acting like a child" thing to a whole other level...

This is fucking bothering me and I can't tell her to fuck off because she's a coworker and I also don't want to sound butt hurt, but I swear to you, when you are working and she starts "kiss kiss kiss" from the desk next to you, all you want is punch her. I ignored her, she keeps doing it or tells you to stop ignoring her. I told her to leave me alone, she starts acting bitchy and gossiping...

What can I do to make her stop this crap?
