Spanish from Spain. Slang form for lesbian. In the starts it was an insult, but by the time it was used like only a slang form to speak about lesbians (nowadays if it is insult or not depends of the tone it was told, like maricon) It have deformations more sweet: bollo, bollito.
Es bollera, que pena que sea chica. (dicho por un chico)
(She is bollera, it's a pitty because she is a good girl. (it was say by a guy))
Me va el rollo bollo.
(I like the bollo way)
