A synonym for "being or turning bisexual" or "getting curious towards one's other sexual side". That term is derogatory and describes bisexuality from the unilateral point of view of an exclusive homosexual and/or heterosexual stand.
Karla is not completely a lesbian. She is rather... mixed up.
Maybe she is bisexual?
Possibly. But we still love each other dearly.
I have no doubt about that
