I have a female coworker (early 20's) who's a fairly cool chick (maybe cause she's bi so thinks like a man?) to hangout with while we're at work. Even though she's got a serious boyfriend, she does tend to flirt with another coworker of mine (older male in his late 30's). She's a HB7 with some daddy issues from what I can tell (openly says she older men - late 30s early 40s and boasted about getting her nipples pierced to myself and a couple other coworkers).

​

She's never flirted with me before but ever since I've started lifting she's slowly started to act differently around me. On Saturday she invited me to go have a drink with her and her friend (other girl) and I declined because I had other plans. The next day we were working and she told me how spent $150 on drinks and how it was great time blah blah blah. Later I was walking to go grab something to eat from a 7-11 and she asked me if I could grab a redbull and beef jerky cause she was broke. Naturally I said absolutely not in a teasing but serious way cause she was just telling me earlier about her hoescapade. When I got back she was really surprised I didn't get her a red bull but one for myself and surprisingly acted playfully upset.

​

Given all of that, would it be a bad idea to smash this coworker a couple times if I'm transferring in the next two months?
