4. A blatant disregard for the boundaries of intimate relationships, including her own.

If you were with a significant other, who didn't know her, that didn't stop her from practically humping your s.o. when she'd hug him/her. She wanted you to know that SHE had the sex appeal and that the best you could offer your s.o. was a nice smile.

She had no boundaries with anyone. Especially the men in our social group. She'd ask married men or coupled men for shoulder massages, she'd comment on their muscles, she'd drape herself on the men any chance she could and they loved it. The women, not so much.
