What does it mean?...

it's a dialect from either hakka or hokkien i think... bo meaning no, or din, whereas jio meaning call or invite...

so literally it means, din call or invite...

but somehow, jio also can mean banana

and when we say to someone bojio, can also mean no banana... ehem... which i would actually say kinda bad and awkward? especially to a guy... :P

so yeah...

Erm... where did you leant this word?
