A Muslim girl who wears the hijab, but does not properly act like a hijabi/is not religious. i.e. drinks, has boyfriends, swears, wears tight clothes, etc.
Person 1: Did you see Sarah making out with Mark last night?
Person 2: Yeah, her dad would freak if he found out. She's such a hoejabi.
"Bro I heard that girl cheated on her boyfriend and told him she doesn't think having sex with someone else is cheating."
"Yeah man, she's Rachel Hoejack."
"Wack. I'm gonna stay away from that one."
A Muslim girl (wears a hijab or a scarf) who acts like a hoe.
Most of the times she's not even a hoe, she is just dating or making out with guys. However, It is considered as a sin because a Muslim girl, especially if she wear a Hijab, should not do that with anyone but her husband.
